Getting calls or texts urging you to dial a 900 number, or seeing 900 on your phone bill? Unlike an ordinary area code, 900 is a North American premium-rate (pay-per-call) prefix: the person who dials it is charged a per-minute or flat fee that is passed to the company running the line. Some 900 services are legitimate, but the prefix is heavily used in billing traps and call-back scams. This guide explains what 900 really is, the scams tied to it, and how to block and report it.
✅ Quick Safety Verdict
Is 900 an official code? Yes. 900 is the official NANP premium-rate code—not a geographic area code and not toll-free. Is it safe? Answering an incoming call is usually free, but never dial a 900 number you do not recognize: you agree to a charge the moment the call connects. Legitimate 900 lines must disclose the price up front, so treat any pressure to “call 900-…” as a red flag.

Common Scams Reported From Area Code 900
Because every 900 call bills the person who dials, fraudsters focus on tricking you into calling or staying on the line:
Call-Back & Missed-Call Bait
A text, voicemail, or robocall urges you to “call 900-… to claim a prize, unlock your account, or avoid a penalty.” Dialing connects you to an expensive per-minute line, and the longer you stay on, the more you are charged—with the money going to the scammer.
Subscription & Billing Traps (Cramming)
Ads for “free” psychic, adult, contest, or tech-support lines bury the 900 per-minute rate in fine print, then run up large charges—sometimes billed straight to your phone bill without clear consent, a practice called cramming.
Text Message (SMS) / Smishing Alerts
Texts pose as a delivery service, bank, or sweepstakes and tell you to call a 900 number to “verify” or “claim.” Never call a number from an unexpected text; contact the company through its official number instead.
How to Identify & Verify Unknown Callers From 900
- Let it ring. Legitimate callers leave a voicemail; most scam auto-dialers do not.
- Search the number. Paste the full 10-digit number into a search engine or a reverse-lookup site to see if others reported it as spam.
- Know the code. 900 is a premium-rate pay-per-call code that charges the caller, not a local line, so it will never be your neighbor’s local number—see our area code 900 reference.
- Call back on an official number. If a caller claims to be your bank or a government agency, hang up and dial the number printed on your card or the agency’s official website—never the number that called you.
- Never share codes. No legitimate caller needs a one-time passcode, PIN, or password read aloud.

Frequently Asked Questions
Is area code 900 a scam?
900 is not a scam by itself—it is the legitimate North American premium-rate code—but because every call charges the caller, it is widely abused in prize, subscription, and call-back scams. Never dial a 900 number you do not recognize.
Does it cost money to call a 900 number?
Yes. Calling a 900 number bills you a per-minute or flat fee set by the service, which appears on your phone bill. Answering an incoming call is normally free, but returning a 900 call is not.
Can I block 900 numbers?
Yes. Most carriers block all 900 / pay-per-call numbers for free—ask your provider to add a “900 block” to your line, and use the phone steps above.
Why did I get a text telling me to call a 900 number?
That is a common bait tactic: the sender profits from the premium charge when you call. Do not dial it, and forward the text to 7726 (SPAM) to report it to your carrier.
