Two number types · One platform
US numbers for OTP codes or long-term use.
kiwiSMS offers Phone Verifications for short-term SMS rentals, and Long-Term Numbers when you want to keep the same line for days or weeks — real wireless, non-VoIP USA numbers.
Two products, one account
Choose the number type that fits your workflow. Most users start with Phone Verifications; switch to Long-Term when you need to hold a line longer.
Phone Verifications
Short-term US wireless numbers for SMS verification. Rent for ~20 minutes, receive multiple codes during that window, and renew the same line if it is still available.
- •Charged only when each SMS is delivered
- •~20 minute rental — multiple codes on the same number
- •Renew if the number is still available
- •Automatic refund if no code arrives
- •Works with Google, Telegram, WhatsApp, and hundreds more
Long-Term Numbers
Keep the same non-VoIP US number for as long as you need — days, weeks, or longer. Built for accounts that send multiple messages or need a stable line.
- •Same number for the full rental period
- •Manual or auto-renew before expiry
- •Optional area code selection
- •Real T-Mobile, Verizon, and AT&T lines
Non-VoIP USA numbers
Real wireless lines — not VoIP — so more services accept your number on the first try.
