If you receive a text message from the three-digit number 889, it is essential to understand that this is an official Short Code used for high-volume, automated communications.
The 889 short code is predominantly associated with T-Mobile in the United States and Puerto Rico. For T-Mobile customers, texts from 889 are typically legitimate, transactional alerts regarding your wireless account. However, due to the prevalence of text scams, all messages from unknown senders—even short codes—should be scrutinized.

Primary Sender: T-Mobile (U.S. & Puerto Rico)
The 889 short code is registered and used by T-Mobile, one of the largest mobile network operators in the North American market. Short codes are highly secure communication channels because they must be rigorously approved by carriers. In most cases, a 3-digit short code in North America is only used by the primary network carrier.
Common Legitimate Messages from 889:
The purpose of the 889 short code is to send crucial, non-promotional alerts about your service. These messages are sent to T-Mobile customers, including those using T-Mobile Home Internet (ISP).
- Data Usage Alerts: Notifications that you are approaching your monthly high-speed data cap or your mobile hotspot limit.
- Account Service Notifications: Information about changes to your plan, service maintenance, or general alerts regarding your account status.
- Verification Codes: Although less common than other short codes, 889 (or similar codes) may be used to send one-time passcodes (OTP) for account login or changes.

Is the 889 Text Message a Scam?
While the sender code 889 is legitimate, the content of the message must always be verified due to a widespread tactic called smishing (SMS phishing). Scammers can electronically spoof a short code or, more commonly, send a message from a regular 10-digit number but reference the legitimate 889 short code to add credibility.
Red Flags to Watch For:
| Red Flag | Description | Action |
| Suspicious Links | The message includes a link asking you to click immediately to “claim a prize” or “verify account details.” | DO NOT click. Legitimate T-Mobile links usually use the official, shortened domain: t-mo.co. |
| Requests for Data | The text asks you to reply with personal information, passwords, bank details, or your Social Security Number. | NEVER reply. T-Mobile or any major company will never ask for sensitive data via unsecured text. |
| Threatening/Urgent Tone | The message creates a false sense of panic, demanding immediate action to prevent an account lockout or service suspension. | Verify the status by logging into your account directly on the official T-Mobile app or website. |

How to Stop Messages from Short Code 889
Since the messages from 889 are usually transactional (essential to account management), you may not be able to opt out of all messages (like security alerts). However, you can manage and report unwanted texts:
Step 1: Manage Communication Preferences
For data usage alerts and other non-security messages, you can often adjust settings directly:
- Log in to your official T-Mobile account via the T-Mobile app or website.
- Navigate to your Account Profile or Communication Preferences
- Adjust which types of SMS alerts you wish to receive about your usage, billing, or plan changes.
Step 2: Report Spam and Block the Sender
If you receive a suspicious text from 889 (or any number) that you believe is a scam:
- Do Not Reply: Replying confirms to scammers that your phone number is active.
- Forward the Scam Text to 7726 (SPAM): All major U.S. carriers (AT&T, T-Mobile, Verizon) use the short code 7726 to collect reports of mobile spam and block similar messages in the future.
- Delete the Message: Once reported, delete the text from your inbox.
Frequently Asked Questions (FAQ)
What if I received a text from 889, but I am not a T-Mobile customer?
If you are not a T-Mobile customer (for example, if you are an AT&T or Verizon customer), a text from 889 is almost certainly a scam or a spoofed message. Delete the message and do not reply, as T-Mobile’s short code should only be recognized by devices on its own network.
Does texting “STOP” to 889 work?
The standard command STOP will unsubscribe you from most marketing or promotional short code programs. While texts from 889 are typically transactional, replying with STOP may stop some non-essential alerts. However, you should not rely on this method if the message is clearly a scam.
Is the 889 short code ever used by AT&T or Verizon?
No. In North America, short codes are generally carrier-specific. While some older data suggests other uses, the consensus is that 889 is officially a T-Mobile code. AT&T and Verizon use different, registered short codes for their account alerts.
