Surfshark Alternative Number

Overview

Surfshark Alternative Number is a paid privacy add-on that gives you a virtual phone number to use instead of your real number. Its simple: when a website, marketplace, app, discount offer or online service asks for a phone number, you give out your Surfshark number rather than exposing the number you use every day.

That matters because phone numbers are much harder to replace than email addresses. If your main email starts getting spam, you can create a new alias, tighten filters, or abandon a secondary inbox. If your main phone number gets into marketing databases, scam lists, broker profiles or leaked account data, the consequences are much more annoying, spam calls, smishing texts, fake delivery messages, WhatsApp scams, cold sales calls, and unwanted contact that follows you across years.

Alternative Number is Surfshark’s answer to that problem. It sits alongside Alternative ID, which creates an alias name, address, date of birth and masked email address, Alternative ID protects the details you type into forms, Alternative Number protects the phone number field.

Overall, Surfshark Alternative Number is a useful privacy tool for people who regularly sign up to websites, sell items online, join promotions, use marketplaces, or give out contact details to strangers. It’s not a full second phone contract, not a business phone system, and not a guaranteed solution for every verification code, it’s best understood as a privacy buffer for ordinary online life.

What Is Surfshark Alternative Number?

Surfshark Alternative Number is a virtual phone number that works through the Surfshark app, letting you receive calls and messages without giving out your personal mobile number. Surfshark describes it as a way to mask your regular phone number from online threats, spam, scams and unwanted exposure.

It isn’t included automatically with every Surfshark plan, this is the most important buying point. Alternative ID is included with Surfshark plans, but Alternative Number is sold separately as a paid add-on, requiring both an active Surfshark subscription and an Alternative Number subscription.

12th July 2026 pricing: Surfshark One starts from £3.57 per month on the 24-month term, with the fuller One Plus bundle from £4.47 per month. Full breakdown of every plan and term below. Remember these prices include the Alternative Number product, which is not included in standard Surfshark plans.

The product is designed for personal privacy rather than business telecoms, useful when a website wants a number but doesn’t truly need your real one, not designed to replace your mobile provider, support a company call centre, or act as a permanent professional line.

At the latest check, Surfshark’s own pages weren’t perfectly consistent on regional availability, some support material stated that Alternative Number currently provides US-based numbers only, with the marketing FAQ also referencing US and Canadian numbers. For UK users, the practical takeaway is the same: don’t expect a UK mobile number. Check the live checkout page and the number selection screen before buying.

How Alternative Number Works

You first need an active Surfshark subscription, new customers can add Alternative Number while buying Surfshark, and existing customers can add it from the Surfshark dashboard or app.

Once purchased, you generate an Alternative Number inside the Surfshark mobile app (under the Antiscam tab on iOS; under Alternative ID then Number on Android). Surfshark says you need to allow access to your microphone, notifications and contacts for the feature to work properly. Messages sent to your Alternative Number appear inside the Surfshark app, while calls are forwarded to your phone and appear like a normal incoming call, a good design choice that avoids making you manage a completely separate phone.

You can copy the number and use it in signup forms, listings, discount accounts, marketplace profiles and other situations where you want to keep your real number private, and you can block, delete or report messages. Surfshark says you can change your Alternative Number once per month, useful if it starts attracting spam, but changing it deletes the old number, so don’t use it carelessly for accounts you may need to recover.

What Alternative Number Is Best Used For

Alternative Number is best for situations where you need to be contactable but don’t want to expose your real phone number, online marketplaces, classified ads, selling second-hand items, discount signups, loyalty schemes, app trials, dating or social platforms, online competitions, event registrations, temporary projects, delivery notes where a number is requested, and websites you don’t fully trust.

It’s particularly useful for marketplace selling, where you often need to communicate with strangers, and for reducing spam risk from companies that ask for a phone number when they don’t really need one. It can also work for low-trust verification, Surfshark says Alternative Number can receive verification messages, although some services may not support virtual numbers, so it may work for some verification flows and fail for others.

Where You Should Not Use Alternative Number

Alternative Number shouldn’t be used for every account. Don’t rely on it for banks, tax accounts, government services, healthcare, insurance, employment checks, business registrations, legal services or critical account recovery, these accounts may need your real identity and a stable long-term number, and losing or changing the virtual number later could make recovery much harder.

Avoid using it as the only recovery number for your main email, Apple account, Google account, Microsoft account, password manager or financial accounts. Also avoid using it to break a website’s terms, deceive people in high-trust transactions, or bypass systems where your legal identity is required. Alternative Number is best for low- and medium-trust interactions, not your most important accounts.

Alternative Number vs Alternative ID

Alternative ID and Alternative Number solve related but different problems. Alternative ID creates a masked identity, alias name, address, date of birth and masked email address, for when a website asks for personal details it doesn’t truly need. Alternative Number gives you a virtual phone number for when a website, app, seller, buyer or stranger asks for a contact number.

The two tools work best together, using only one still leaves an identifiable trail through the other channel. That said, only Alternative ID is included with Surfshark plans by default; Alternative Number costs extra, and that distinction should be clear in any buying decision.

Does Alternative Number Work for Verification Codes?

Surfshark says Alternative Number can be used to receive verification messages, but some services may not support virtual phone numbers, banks, messaging apps, social networks, crypto exchanges, payment services and high-risk platforms may reject VoIP numbers, shared number ranges, or numbers identified as virtual. This doesn’t make Alternative Number useless, but it means you shouldn’t buy it only for verification code bypassing, buy it for privacy, spam reduction, marketplace safety and lower-risk signups, and treat verification support as useful when it works rather than guaranteed when it matters.

Can Alternative Number Replace a Second SIM Card?

For most people, no. A second SIM card gives you a real mobile number from a carrier, potentially supporting broader verification, outbound calling, mobile network access and long-term number stability. Alternative Number is a virtual privacy number inside Surfshark’s ecosystem, easier to set up and more private for casual use, but less suitable as a full second line. If your goal is simply to stop handing out your real mobile number to random websites and strangers, Alternative Number is the cleaner option; for business calls, client communication, WhatsApp or permanent account recovery, a real second SIM or business phone service may be more reliable.

Pricing and Refund Warning

Surfshark Alternative Number is a paid add-on, and pricing can vary by plan, region, currency and promotion, check the live Surfshark checkout before buying.

There is also a refund warning worth flagging clearly: Surfshark’s general plans usually come with a 30-day money-back guarantee, but Surfshark’s refund policy and Terms of Service state that purchases associated with Alternative ID services, including Alternative Number, are non-refundable. Don’t assume you can test Alternative Number in the same risk-free way as the main Surfshark VPN plan, check the available number region, confirm the price, read the refund terms, and make sure the feature matches your use case before adding it.

Advantages

• Protects your real mobile number: phone number exposure can create long-lasting spam and scam problems.
• Convenience: no second SIM, second phone, or separate telecom account needed.
• Marketplace safety: useful when dealing with strangers online for listings, sales, rentals and events.
• Spam control: change the number once a month if it becomes noisy.
• Pairs well with Alternative ID: together they mask both identity fields and the phone number field.

Disadvantages

• Number availability: UK users shouldn’t expect a UK number; Surfshark’s materials point mainly to US (and sometimes Canadian) numbers.
• Not included for free: a separate paid add-on.
• Refund position: may be non-refundable even though main Surfshark plans normally have a 30-day guarantee.
• Verification reliability: some services reject virtual numbers, so it shouldn’t be the only recovery number for important accounts.
• Not a full phone plan: not ideal for business use or as a permanent second mobile line.

Who Should Use Surfshark Alternative Number?

Alternative Number is best for privacy-conscious users who already use Surfshark or plan to buy it anyway, useful for people who sign up to lots of sites, sell items online, join promotions, use online marketplaces, or dislike giving their real number to strangers. It’s also a good fit for people who already receive a lot of spam calls and want to stop making the problem worse, though it won’t remove your real number from existing spam lists.

More caution is warranted if you need a UK number, guaranteed verification support, a business phone line, or a long-term second mobile identity, a real second SIM, business VoIP provider, or dedicated phone number service may be better.

Verdict

Surfshark Alternative Number is a useful privacy add-on, but it needs to be bought with the right expectations. It isn’t a full replacement for a second SIM card, and it isn’t guaranteed to work with every verification system, it’s a virtual number designed to protect your real mobile number from unnecessary exposure.

Used correctly, it makes a lot of sense for online signups, listings, marketplaces, discounts and casual accounts, and becomes even more useful paired with Surfshark Alternative ID. For UK users, the main limitation is regional, assume it’s mainly a US number product unless the checkout shows otherwise. If you already use Surfshark and understand the non-refundable add-on warning, it’s worth considering; if you need a guaranteed local UK number or a full second line, look elsewhere.
