Why email providers ask for a phone number
Email providers ask for a phone number to stop automated signups. When you create a new inbox, a confirmation code is sent by SMS to the number you entered. Using a one-time US number from ZapSMS means that code lands on your order page instead of on your personal phone, so your real number stays private while the new inbox is created.
How ordering works for email verification
Pick the email provider you are signing up for, place a one-time order, and a fresh non-VoIP US number is issued for that verification. The confirmation code appears on your order page, so you do not need a separate phone or SIM. No subscription is required — you pay per number. This category currently lists 3 services: Gmail from $1.75 per verification, Outlook from $3.49, and Proton Mail from $3.99. Stock is shown next to each service and changes as numbers are used.
Numbers for Gmail, Outlook, Proton Mail and others
The email category covers Gmail, Outlook, Proton Mail and other email providers. Because each order gets a fresh non-VoIP US number, you can verify more than one inbox without reusing the same number. If you need a number that stays yours for longer than a single code, see renting a US phone number for a day up to a year. For other categories and one-time verification generally, browse all SMS verification services.
What a one-time number does not do
A ZapSMS number in this category receives a single SMS confirmation code for your email signup. It is not a calling line, and it is not designed to hold an inbox permanently — for lasting access to the same number, choose a rental instead. If you are unsure how one-time SMS verification works, the guides explain it. Prices on this page are per verification and start lower in other categories, from $0.50 — see pricing.
Frequently asked questions
Do I need a subscription to verify an email address?
No. ZapSMS is a prepaid storefront, so you buy a one-time number per verification and there is no recurring subscription.
Is the number I get a real US number?
Yes. ZapSMS issues non-VoIP US numbers, which is what email providers expect when they ask for a phone number at signup.
Where do I see the confirmation code?
The SMS confirmation code arrives on your order page, so you can copy it straight into the email provider's signup form.
Can I verify more than one inbox?
Yes. Each order gets a fresh number, so you can verify multiple email accounts without reusing one number.
