Area code 720: scam texts, spam calls & where it's from
Area code 720 is a real the Denver metro area code (United States). But a text or call from a 720 number is very often spam or a scam: numbers are cheap to spin up and easy to spoof to look local. The area code alone never proves who is really contacting you.
Where is area code 720?
Area code 720 covers the Denver metro area, in the Mountain Time zone. It's an overlay code, sharing the same geographic area as 303, so local numbers there can start with any of them. Cities and areas it serves include Denver.
Why am I getting texts from a 720 number?
If a 720 text landed out of nowhere, it's almost always one of these:
- Mass smishing. Scammers blast text-phishing messages to huge lists of random numbers — a 720 sender doesn't mean it's local or that they know you.
- Spoofing. The 720 number on your screen can be faked so the text looks like it's from your area and you're more likely to trust it.
- "Wrong number" openers. A friendly "Hi, is this Sarah?" text is bait to start a chat that leads to a crypto or romance scam.
Is a text from 720 a scam? How to tell
- It claims to be a bank, delivery service, toll agency, or government office and creates urgency.
- It asks you to tap a link, pay a small fee, or "verify" card, login, or one-time-code details.
- The link isn't the company's real website — often a look-alike with extra words or an odd ending.
- It arrived unexpectedly, uses a generic greeting, or pressures you to act right now.
What to do about a 720 text or call
- Don't tap any link and don't reply — not even "STOP" to a sender you don't recognise.
- Don’t call back from the message. If it claims to be a company you use, find the official number yourself and contact them that way.
- Forward spam texts to 7726 (SPAM) so your carrier can block the sender, then delete the message.
- Block the number on your phone, and report it to the FTC at reportfraud.ftc.gov.

Getting 720 texts on your iPhone or Android
You can cut down unknown-sender spam without waiting for the next one. On iPhone, open Settings › Apps › Messages and turn on Filter Unknown Senders to move texts from numbers you don't know into a separate list, then use Report Junk under any scam text. On Android, open Messages › settings › Spam protection and switch it on, and use Block & report spam on the conversation. Neither stops a determined scammer, so still treat any unexpected 720 message as suspicious.
Frequently asked questions
Is area code 720 a scam?
An area code can't be a scam by itself — 720 is a normal code for the Denver metro area. But scammers send spam texts and spoof 720 numbers constantly, so judge the message, not the area code. If it asks you to pay, verify, or tap a link, treat it as a scam.
Is 720 spam?
A lot of texts and robocalls from 720 are spam. Scammers favour local-looking numbers because you're more likely to answer. Don't tap links, don't reply "STOP" to a number you don't recognise, and forward spam texts to 7726 (SPAM) so your carrier can block the sender.
Where is area code 720?
Area code 720 covers the Denver metro area and is in the Mountain Time zone. It overlays the same area as 303.
Why am I getting text messages from a 720 number?
Usually one of three reasons: a mass smishing (text-phishing) campaign blasting random numbers, a scammer spoofing a 720 number so it looks local, or a "wrong number" opener that tries to start a conversation. If you weren't expecting it and it contains a link or a request, it's almost certainly a scam.
I keep getting 720 texts on my iPhone — how do I stop them?
On an iPhone, open the message (don't tap any links), tap the sender, and choose Block this Caller. You can also turn on Settings › Apps › Messages › Filter Unknown Senders to move texts from numbers you don't know into a separate list, and use "Report Junk" under the message to flag it to Apple and your carrier.
Should I call or text 720 back?
Not from the message. If it claims to be a company you use, look up the official number yourself and call that instead. Replying or calling back can confirm your number is active and lead to more spam.
