Sometimes you want to send a text message without revealing your phone number. Whether for privacy or professional reasons, blocking your number on iPhone texts can help keep your identity hidden. However, many developers and users find it confusing how to do this effectively on iOS devices.
This guide explains how to block your number when sending texts from an iPhone. It covers built-in iOS settings, carrier options, and third-party apps that help you send anonymous or private messages. Follow these steps to control your number visibility when texting.
How do I block my number on iPhone texts?
You can block your number on iPhone texts by enabling the "Show My Caller ID" setting to off in your phone settings or using carrier codes to hide your number. Alternatively, third-party apps can send anonymous texts.
To block your number on iPhone texts, start by disabling caller ID in Settings > Phone, then confirm with your carrier if necessary. For SMS, hiding your number depends on carrier support.
iPhones do not have a native setting to block your number specifically for SMS texts. The "Show My Caller ID" option affects calls but not SMS. This means that while you can hide your number during calls, SMS messages usually still show your number unless your carrier supports blocking it or you use third-party apps.
To disable caller ID for calls, go to Settings > Phone > Show My Caller ID and toggle it off. This setting prevents your phone number from showing on outgoing calls but does not affect SMS messages.
For SMS, some carriers allow you to block your number by dialing a prefix code before the recipient's number. For example, in the US, dialing *67 before the number hides your caller ID for that call, but this does not apply to SMS texts.
To block your number on texts, you can use third-party messaging apps like Signal or Burner, which allow sending messages without revealing your personal phone number.

- Third-party app installation: For anonymous texting, you may need to install apps from the App Store that support private messaging.

How do I disable caller ID on iPhone for calls and texts?
Disabling caller ID on iPhone is straightforward for calls but limited for texts. To hide your number during calls, open Settings > Phone > Show My Caller ID and toggle it off. This prevents your number from appearing on the recipient's caller ID.
However, this setting does not affect SMS messages. Your phone number will still appear in texts unless your carrier supports blocking it or you use third-party apps.
Some carriers allow blocking caller ID on a per-call basis by dialing a prefix like *67 before the number. This method does not apply to SMS messages.
To check if your carrier supports blocking caller ID for texts, contact customer support or visit their website. Some carriers offer paid services or settings to enable anonymous texting.
For SMS privacy, consider using apps like Signal or WhatsApp, which send messages over data and do not expose your phone number to recipients unless you share it.
