Did you just get a random 47458 text message on your iPhone or Android? Maybe it was a 47458 Yahoo verification code you never requested. If so, you’re right to be suspicious. Every day, thousands of people receive these confusing texts and wonder: Is this a legitimate message or a sophisticated scam?
This guide will break down everything you need to know. We’ll explain what the short code 47458 is, who uses it, and how scammers are weaponizing it. Most importantly, we’ll give you a clear, step-by-step plan to protect yourself.

What Is the Text Code 47458? Is It a Real Phone Number?
First, let’s clarify what you’re seeing. The number 47458 is not a standard phone number; it’s an SMS short code. Businesses use these 5 or 6-digit numbers to send high volumes of text messages (a practice called A2P, or Application-to-Person, messaging).
So, is it legitimate? Yes. The 47458 short code is officially leased and used by major corporations. The most commonly reported users are:
- T-Mobile: Customers often receive a 47458 text message from T-Mobile regarding billing, account changes, or network notifications. If you’re a T-Mobile customer, a short code 47458 text message could be authentic.
- Yahoo: This is one of the most frequent uses. Yahoo sends verification codes from 47458 when you try to log in, change your password, or recover your account. A 47458 Yahoo text is a key part of their security.
Other services, like the financial app Wealthsimple, have also been known to use the 47458 text number. The problem isn’t that the number is fake—the problem is that scammers are exploiting its legitimacy.
The “Verification Code” Scam: How Fraudsters Use 47458
Here is the crucial part you need to understand. If you receive an unsolicited verification code from 47458, it’s almost certainly part of a scam. Here’s how it works:
- The Hacker Gets Your Info: A scammer finds your email address and phone number from a public record or a corporate data breach.
- They Trigger the Code: The scammer goes to the Yahoo or T-Mobile login page, enters your email, and clicks “Forgot Password.” This prompts the real Yahoo or T-Mobile service to send a real verification code to your phone from the official 47458 short code.
- The Follow-Up Attack: You now have a confusing text from 47458 on your phone. Moments later, the scammer calls or texts you, pretending to be from “Yahoo Fraud Protection” or “T-Mobile Security.” They’ll say something like, “We’ve detected a suspicious login. To secure your account, please read me the code we just sent you.”
- You Lose Control: If you give them the code, it’s game over. The scammer enters it into the password reset form and instantly takes over your account.
This is why the context of the message is everything. If you did not just try to log in to one of these services, the verification code is not for you. It was triggered by a criminal.
What About Other Short Codes Like 58083, 66458, and 99467?
This issue isn’t limited to just one number. You might see the same scam using other codes.
- 58083 Text Message: This short code is legitimately used by the financial service Affirm. Scammers use the exact same tactic: they trigger a real 58083 short code text message and then try to trick you into sharing the code.
- 66458 Short Code: This code is used by the ParentSquare school communication app. If you’re a parent, a text from this number could be a real school alert. However, scammers also use it for phishing attempts.
- 99467 Short Code: This number is more mysterious and doesn’t appear in official short code directories, making any text from it highly suspicious and likely a spoofed number.
Your 5-Step Defense Plan: What to Do Right Now
If you received a suspicious 47458 text, follow these steps immediately.
- DO NOT REPLY. DO NOT CLICK. Never reply to the message, not even with “STOP.” A reply confirms your number is active, inviting more spam. Absolutely do not click any links in the text.
- BLOCK THE NUMBER. On your iPhone or Android, you can easily block the 47458 phone number directly from the message. This will prevent further texts from that specific code.
- REPORT THE MESSAGE AS SPAM.
- On your phone: Most messaging apps have a “Report Junk” or “Report Spam” option.
- To your carrier: Forward the entire spam text to the number 7726 (which spells SPAM). This is a free service for most carriers (AT&T, T-Mobile, Verizon) that helps them fight spammers at the network level.
- SECURE YOUR ACCOUNTS. Go directly to any account mentioned in the text (like Yahoo). Do not use any links from the message. Change your password immediately and review your security settings for any unrecognized activity.
- NEVER SHARE VERIFICATION CODES. This is the golden rule. No legitimate company will ever call you and ask you to read a verification code back to them. That code is for your eyes only.
