If you're about to set up a virtual number for WhatsApp Business, the "which country should I pick" question has a different answer depending on what you need it for: looking for the cheapest number isn't the same as looking for the one that best serves your actual customers.
First: pick the country where your customers are, not the cheapest one
The most common mistake is focusing only on price and forgetting that a number's country code communicates something to whoever sees it. A customer in Mexico who sees a number with a Spanish country code may hesitate before messaging, even though the service behind it is exactly the same. If you're serving a specific market, that's your first criterion — saving a few euros a month doesn't make up for the friction of a number that doesn't "fit" your audience.
That said, within the countries relevant to your business, there are real differences worth comparing.
What varies from country to country
- Monthly fee: set by the local carrier, and it can vary quite a bit — we cover this in more detail in how much a virtual number for WhatsApp Business costs.
- Available number type: local, mobile, or toll-free, depending on the country — not every type exists in every market.
- Included minutes and overage price: each country has its own bundle and its own extra-minute rate.
- General-purpose SMS: only the United States and the United Kingdom support it today, with caveats — in the US, sending requires a brand registration (10DLC) on top of receiving, which does work from day one; in the UK, sending has a throughput limit meant for normal business use, not mass campaigns.
For most businesses that just need a working WhatsApp Business (without depending on general-purpose SMS), these SMS differences don't matter — verification works the same in every country in the catalog.
Minutes, overage, and paperwork, country by country
Here's the real data on included voice minutes per month, the overage rate per extra minute, and what paperwork the carrier requires to activate the number (audited live against Telnyx's actual requirements, not a generic table) in some of the most-checked countries. The number's monthly fee is shown live in the store (it varies by number type), but these minute bundles, overage rates, and paperwork requirements are fixed per country and local-number type:
| Country | Minutes included/mo | Overage per extra minute | Paperwork to activate |
|---|---|---|---|
| Canada | 22 min | €0.03/min | None, activates instantly |
| Ireland | 17 min | €0.08/min | Address in the number's own area |
| United States | 20 min | €0.03/min | None, activates instantly |
| Portugal | 13 min | €0.03/min | Address in the number's own area |
| Slovakia | 11 min | €0.04/min | Address in the number's own area |
| Poland | 9 min | €0.04/min | Address in the number's own area |
| Netherlands | 8 min | €0.05/min | Address in the number's own area |
| Norway | 8 min | €0.05/min | Address in that country (any area) |
| Spain | 6 min | €0.06/min | Address in the number's own area |
| United Kingdom | 5 min | €0.04/min (+2 SMS included, €0.10/SMS overage) | Address in that country (any area) |
| Sweden | 5 min | €0.08/min | Address in the number's own area |
| Mexico | No minutes included | €0.05/min from the first minute | Physical address, any country |
| Colombia | No minutes included | €0.03/min from the first minute | Physical address, any country |
| Chile | No minutes included | €0.79/min from the first minute | Physical address, any country |
| Switzerland | No minutes included | €1.02/min from the first minute | Address in the number's own area |
The difference between countries isn't random: countries with more included minutes tend to have a lower wholesale cost for InBoxIA (and therefore margin to bundle free minutes), while in markets like Switzerland or Chile, where the wholesale cost per minute is high, no free minutes are included and you pay the real rate from minute one. If your business makes a lot of voice calls (not just WhatsApp), this matters as much as the monthly fee.
What each paperwork (KYC) level actually means
The carrier requires a different level of identity verification depending on the country, and it doesn't matter how fast you want to activate your number: if the requirement isn't met, verification gets rejected and the number can't activate. There are four levels:
- No paperwork: the number activates instantly, nothing to upload. This is the case for the United States and Canada, among others.
- Address in the number's own area: the strictest requirement — the address you upload (a bill, ID, or passport) has to match the exact geographic area of the prefix you pick. This is the case for Spain, Portugal, Sweden, the Netherlands, Switzerland, Ireland, Slovakia, and Poland, among others. If your business doesn't have a real address in that specific area, pick the city with the most availability before buying, not after.
- Address in that country (any area): a real address anywhere in the country is enough, without having to match the prefix's area. This is the case for the United Kingdom and Norway.
- Physical address, any country: the most flexible requirement — you can use an address in your own country even if the number is from another one. This is the case for Mexico, Colombia, Chile, and other Latin American markets.
This is checked live when you pick a country and number type in the virtual numbers store — before buying, you'll see exactly what paperwork will be required for that specific number.
Common cases, by business type
A local business serving a single country: the criterion is simple — a number from that same country, so the country code doesn't raise doubts.
A business selling to several countries from one HQ: here it's worth having one number per main market (see the example in WhatsApp Business API for companies operating in multiple countries), instead of forcing every customer to message a single foreign number.
A business that needs transactional SMS on top of WhatsApp: if your operation depends on sending SMS (not just WhatsApp) outside the US or UK, today it's worth complementing with a local physical SIM for that specific case, and using the virtual number for every other line.
