Short answer
For most people who need one code for WhatsApp, Telegram, Google, ChatGPT or a similar app, the best option is a paid service that gives you a private number for a few cents and refunds you when no code arrives. CoveSMS works that way: over a thousand apps in close to 200 countries, prices from a few cents, the price back to your balance automatically if no code arrives within 20 minutes, and top-ups from $2 by card or crypto.
The four kinds of service
- Free receive-SMS websites: public inboxes anyone can read. Free, but the numbers are reused by thousands of people, so most apps reject them.
- Large number marketplaces (sites in the style of 5sim or SMSPool): huge catalogs and low prices, usually with crypto payments; quality and refunds vary by seller and country.
- US-only rental services (in the style of Textverified): American non-VoIP numbers, often more expensive, good when an app only accepts US numbers.
- CoveSMS: a private number per verification in close to 200 countries, several servers to choose from, automatic refunds, card and crypto payments, and a REST API.
How we compared them
- Privacy: can anyone else read your code?
- Acceptance: do apps take the number, or block it as reused or VoIP?
- Refunds: what happens to your money when no code arrives?
- Price and minimum top-up: can you test with a few dollars?
- Payment: card, Apple Pay, Google Pay, crypto, local methods
- Coverage: how many countries and apps
- API: can a developer or reseller buy numbers in bulk?
Free receive-SMS websites
Best for: curiosity, or an app that doesn't care about the number. Avoid for: anything you want to keep, because everyone can read the code and someone else can take over the account with it.
Number marketplaces
Best for: experienced users who buy a lot and pay in crypto. Watch out for: high minimum deposits on some sites, interfaces built for resellers, and refund rules that differ by seller.
US-only rental services
Best for: apps that only accept US non-VoIP numbers, or a number you need to keep for days. Watch out for: higher prices per code and no other countries.

Which one should you pick?
- One code for WhatsApp, Telegram, Google, ChatGPT, Discord or a dating app: CoveSMS or a marketplace, never a free inbox
- An app that only accepts US numbers: a US non-VoIP number (CoveSMS has US numbers on several servers)
- Hundreds of codes for testing or resale: a service with an API and volume prices
- An account you'll need to recover in a year: your own SIM or eSIM, not a rented number
Before you buy anywhere
Check the price for your exact app and country, top up the minimum, and buy one number first. Use rented numbers for privacy and testing, not to break an app's rules.
