Virtual numbers let an online store take calls and texts in dozens of countries without SIM cards or offices, but they only pay off when someone answers. Use them for conversational support and local presence, and run marketing texts through a registered, consent-based SMS platform instead.
Buying a virtual number takes an afternoon. Keeping the promise it makes, that a human will pick up, is the part that decides whether it builds trust or quietly erodes it.
In early 2025, Forethought surveyed 2,243 US adults about customer support and found that 65% believe a phone call is the fastest way to resolve a service issue. The same research found that in retail, chat is the channel shoppers favor most. Both findings hold at once, and together they describe phone support in ecommerce better than any vendor pitch: most shoppers will never call you, but the one waiting on a $600 order that has not arrived, or weighing a custom piece they cannot return, wants to know a human is reachable.
That is the real job of a business number, and it is why cloud telephony has become the default way online stores add one. Switching to virtual numbers for calls and SMS through a provider like Freezvon lets a store route calls and texts to a remote team, add local numbers in new markets, and add lines for peak weeks without SIM cards, landlines, or offices.
The number itself is the easy part. What decides whether it helps or hurts is who answers it, which texts you send from it, and whether US carriers will deliver those texts at all. This guide is written for founders and support leads between roughly $500K and $10M a year. It covers where virtual numbers earn their cost, where a dedicated SMS platform does the job better, and what to set up first at your stage.
A virtual number is a phone number with no SIM card or copper line behind it: calls and texts arrive over the internet and are routed, by rules you set, to wherever your team actually works. When a shopper dials it, the provider’s cloud platform receives the call and forwards it. SIP forwarding sends the call to a softphone app on a laptop, an IP desk phone, or a browser dashboard. Forwarding to a regular mobile or landline lets an owner take calls on their own phone without ever publishing a personal number. Ring groups can ring several people at once or cycle through them in order, so the caller reaches whoever is free. Inbound texts can land in a web portal, forward to an email inbox, or pass into your own systems through an API.
The detail most buyers miss is that not every number does everything. Freezvon, for example, sells numbers by capability: calls only, SMS only, calls and SMS, calls and fax, and toll-free. If you want one public number that both rings and receives texts, you have to buy that specific type, and it is not offered in every country. Freezvon also says most numbers connect within 24 hours, some mobile numbers take up to five days, and certain countries require a passport, local ID, or proof of a local address before a number goes live.
If you are doing under $500K a year, the right setup is usually the simplest one: a single number that forwards to the owner’s mobile during business hours and sends voicemail to email after hours. Everything else in this guide is something to add once that one line is answered reliably.
Phone and text support earn their cost at three moments: pre-purchase questions on high-consideration orders, delivery problems, and returns or exchanges, because those are the moments when a shopper’s money feels at risk and a typed reply feels too slow. In the Forethought survey, respondents said they turn to the phone when an issue is urgent, complex, or emotionally charged, and 58% said they feel better understood when they can explain a problem out loud.
That maps directly onto ecommerce. A buyer checking whether a sofa fits through a 30-inch doorway, whether a ring can be resized after purchase, or whether a gift will arrive before Friday is not browsing. They are one answer away from buying or leaving, and a two-minute call often settles it faster than three rounds of email.
Texting fills a different gap, and Shopify’s built-in texting is narrower than many merchants assume. According to Shopify’s help center guidance on SMS notifications, a customer who checks out with a phone number instead of an email receives a single order confirmation text, gets no shipping updates by SMS, and cannot reply to that message. The moment a customer wants to text back “can you deliver Thursday instead?” or “I typed the wrong apartment number,” you need a two-way number connected to a person or a helpdesk.
The pattern that shows up again and again with stores in the $500K to $2M range is putting a phone number on the site before deciding who answers it. An unanswered local number is worse than no number, because the shopper has now tried to reach you and failed. Publish the number where the stakes are highest (high-ticket product pages, the order status page, and the returns page) and staff it during the hours your orders actually come in.
Send conversational, one-to-one texts from a virtual number, and send marketing campaigns and automated flows such as cart recovery from an SMS platform connected to your Shopify store. The reason is data. A cart recovery text needs to know the cart was abandoned, a shipping text needs the fulfillment event, and a campaign needs the consent status and opt-out history of every subscriber. A standalone number knows none of that.
The revenue split shows why this matters. Klaviyo’s 2026 SMS benchmarks, drawn from more than 183,000 customers, show automated SMS flows make up 7.6% of sends yet drive 45.2% of SMS revenue, with flow click rates near 10%, roughly double those of campaigns. Those are event-triggered messages that fire from store data. For stores that want to stay native, Shopify Messaging can send SMS marketing campaigns to opted-in customers, but only to recipients in 12 supported countries, including the US, Canada, and the UK.
Two claims from typical virtual number pitches deserve a correction. The first is the 98% SMS open rate. It appears in countless sales decks, but SMS carries no tracking pixel, so a text open cannot actually be measured. Judge texting by clicks, replies, and revenue instead. The second is using your own number for checkout passcodes. On a standard Shopify store you do not need to: Shopify customer accounts sign shoppers in with a one-time six-digit code sent by email, and Sign in with Shop uses the shopper’s Shop credentials and passkeys. Passcodes from your own number matter mainly for custom apps, headless builds, or portals that run outside Shopify’s sign-in.
What a virtual number does well is the human thread: a customer replying to fix an address, or an agent confirming a delivery window. Keep those conversations on the support number and keep broadcast messages in the platform built for them.
Before a 10-digit US business number can text customers, it must be registered under A2P 10DLC, and every marketing text needs the recipient’s prior consent. Twilio’s A2P 10DLC documentation explains that US carriers treat texts sent from a messaging provider’s number as application-to-person traffic, and that anyone sending SMS over a 10-digit number to US recipients from an application must register. Registration has two parts: a Brand, which identifies your business and generally requires a tax ID, and a Campaign, which describes your messages and how people opt in and out. Toll-free numbers and short codes sit outside 10DLC and go through their own verification.
Skipping registration does not mean slower delivery. It means no delivery. Twilio blocks messages sent to US numbers from unregistered 10-digit numbers, and the carrier rules behind that block apply whichever provider you use. Registration review takes days to weeks, so start before you need it.
That leads to the question to ask any provider before buying a US number, Freezvon included: can this number be registered for A2P 10DLC, and who submits the Brand and Campaign? If the answer is unclear, use that number for voice only and send US texts from a platform that handles registration for you.
Registration does not replace consent, and a phone number collected at checkout is not the same as permission to send marketing texts. Shopify’s SMS campaign requirements point merchants to the TCPA in the US, GDPR and the ePrivacy Directive in the EU, and PECR in the UK, and require your terms to state message frequency, that data rates may apply, and how to opt out. None of this is legal advice. If texting is a meaningful revenue channel, have counsel review your opt-in language. This is also where premature complexity bites stores in the $500K to $2M range: a second texting tool running beside your main SMS platform, sending from an unregistered number to a list with no clear consent record, is a deliverability problem and a legal exposure at the same time.
A local number in a new market earns its cost when you already have meaningful order volume there and someone who can answer during that market’s business hours. Shoppers rarely pay international calling rates to ask a pre-sale question. Providing localized virtual numbers means a buyer in Manchester dials an ordinary UK number while your team picks up the call online, wherever they sit. Freezvon lists numbers in more than 120 countries and 4,100 destinations, which covers the major markets most Shopify brands ship to.
Local numbers also let a small team stretch its hours. Route the UK number to a UK-based contractor during their day and to a North American teammate in the evening, and a caller at 6pm London time still reaches a person. A short language menu (“For English, press 1. Para español, oprima 2.”) sends callers straight to a fluent agent, provided you actually have one.
Toll-free numbers do a different job. They cost the caller nothing within the country, which suits national ad campaigns and site-wide headers, and they carry far more capacity by default. Freezvon says its 800 numbers support up to 100 simultaneous incoming calls, against two for a standard landline number.
The discipline is sequencing. The same logic that applies to expanding into new countries one market at a time applies to phone coverage. As an illustrative threshold, if 15% or more of your orders ship to the UK, a UK number staffed during UK hours is a reasonable next step. Buying numbers for Germany, Australia, and Japan before anyone can answer in those time zones only multiplies the lines going to voicemail.
Keep phone menus to three options or fewer, route calls by business hours, and buy enough simultaneous channels for your busiest hour, because callers abandon long menus and busy signals quickly. In the Forethought survey, 46% of consumers said they would disconnect after navigating more than four menu selections, and more than 10% said they give up after one or two. “Press 1 for order status, 2 for returns, 3 for everything else” is plenty for most stores.
Capacity is the setting most merchants never check. A virtual number is not automatically unlimited. Freezvon states that by default its mobile numbers have one channel for incoming calls, landline numbers have two, and 800 numbers have up to 100, with multichannel numbers available when you need more. If three people call during a flash sale and your number has two channels, the third hears a busy signal. Check the channel count before peak season, not during it.
Freezvon’s virtual PBX covers the standard toolkit: IVR menus, call queues with hold music, internal extensions, voicemail to email, and call recording, which helps with training and with settling order disputes. If you record calls, announce it at the start, since recording consent rules vary by state and country.
The last decision is where calls land. If your team already works in a helpdesk, forwarding usually beats a separate phone app. Gorgias supports forwarding calls from an external provider into a Gorgias number, so each call becomes a ticket alongside the customer’s Shopify order history. One trade-off to know: outbound calls placed from Gorgias show the Gorgias number rather than the forwarded one, so a customer may see two numbers from you.
Freezvon fits stores that need local numbers in many countries at a predictable fixed cost, helpdesk-native voice such as Gorgias Voice fits teams that want every call handled as a ticket, and AI phone platforms like Consio fit North American stores that want after-hours AI answering and outbound checkout recovery. They are not interchangeable, and the right choice depends on where your customers are and who answers.
Freezvon’s pricing has three parts: a one-time connection fee, a subscription you can prepay for one, three, six, or 12 months at a 2% to 18% discount, and per-minute charges for forwarding and outgoing calls that vary by destination. There is no free trial on numbers, though Freezvon runs a free DID promotion for testing call quality. Model forwarding costs at your real call volume before comparing against flat per-seat tools. By contrast, Gorgias Voice is billed as an add-on to a Gorgias helpdesk plan, and Consio starts at $30 a month for 100 minutes.
Do your own diligence on fit. Freezvon holds a 3.5 out of 5 TrustScore across 130 Trustpilot reviews, split sharply between five stars (54%) and one star (33%), with only two reviews in the past 12 months. The complaints cluster around sold-out destinations, SIP setup, and numbers that failed as verification numbers for other apps, which Freezvon says is not an intended use. None of that rules it out for inbound customer support, but it argues for starting with one number and testing call quality before moving your main line.
Start with one staffed number before you buy many: under $500K a year, forward a single number to a mobile; from $500K to $2M, route one number into your helpdesk; above $2M, add local and toll-free numbers only where order volume and staffing justify them.
Under $500K a year, the goal is reachability, not a phone system. Use one number with business hours forwarding to the owner, voicemail to email after hours, and the number published on high-ticket product pages and the order status page. Leave marketing texts to your email and SMS platform.
From $500K to $2M, route that number into your helpdesk so calls become tickets, add two-way texting for delivery and address fixes, and register for 10DLC if you text US customers. Before adding a standalone phone system, compare it against the wider field of helpdesk and phone support apps, since you may already pay for one with voice built in. Resist the second marketing SMS tool.
From $2M to $10M, add a local number in your one or two largest international markets, a toll-free line for national campaigns, enough channels for your peak hour, call recording for quality review, and language routing where you have fluent staff. Above $10M, treat phone as an operation: coverage schedules per market, response targets, call data feeding your CX reporting, and a serious look at AI answering for after-hours volume.
Run every step through one question: will this matter in 18 months? A staffed line for high-consideration purchases will. A number in every country you ship to, before anyone can answer those calls, will not.
A virtual phone number is a business number that runs over the internet instead of a SIM card or landline, so calls and texts can be routed to softphones, mobiles, or a helpdesk wherever your team works. Online stores use them to publish a local or toll-free support line, add numbers in new countries without opening an office, and ring several agents at once during busy periods. Providers such as Freezvon sell numbers by capability (calls, SMS, or both), so confirm the number type supports texting if you need it. Most numbers connect within a day, though some countries require identity documents or proof of a local address first.
You can text US customers from a virtual number only if that 10-digit number is registered under A2P 10DLC and your customers have agreed to receive the messages. US carriers treat texts from a provider’s number as business traffic and block messages from unregistered 10-digit numbers. Registration requires a Brand, which identifies your business, and a Campaign, which describes your messages and opt-in process. Before buying a US number, ask the provider whether it can be registered and who submits the paperwork. Marketing texts also need prior consent under the TCPA, and a phone number entered at checkout does not count as consent on its own.
A virtual number usually costs a one-time setup fee plus a monthly subscription, with per-minute charges for forwarding and outgoing calls on top. Freezvon uses that model and discounts subscriptions by 2% to 18% when you prepay three, six, or 12 months; exact prices depend on the country, number type, and forwarding destination. Helpdesk and AI phone tools price differently: Gorgias Voice is a paid add-on to a Gorgias helpdesk plan, and Consio starts at $30 a month for 100 minutes. Compare total monthly cost at your real call volume, including forwarding minutes, rather than the headline number fee.
Yes, but only if you can answer during clearly stated hours and route everything else to voicemail or text with a promised response time. An unanswered number damages trust more than having no number, because the shopper tried to reach you and failed. Publish the number where stakes are highest: high-ticket product pages, the order status page, and the returns page. State your hours next to it, set after-hours calls to voicemail that arrives by email, and reply within one business day. As call volume grows, add a second person to a ring group or route the number into your helpdesk.
Connect a virtual number to a helpdesk by forwarding its calls to a number the helpdesk provides, or by porting the number into the helpdesk entirely. Gorgias supports both: forwarded calls from an external provider arrive as voice tickets, while porting makes Gorgias your carrier. Forwarding is faster and keeps your existing number and provider, but outbound calls from Gorgias show the Gorgias number rather than your forwarded one, and whether the caller’s own number displays depends on your provider. Test a few calls, confirm that recordings and caller ID come through, then publish the number on your store.
