This internal error can be frustrating, especially if you think you’ve set everything up correctly. The user in question had gone through the process of adding test phone numbers in the Firebase console, but when it came to US numbers, the situation turned complicated.

Identifying the Core of the Issue

Upon reaching out to the Firebase support team, the root of the problem was identified: Incorrect phone number formatting. Here are the key findings from the conversation:

Test Numbers: You cannot use existing phone numbers that belong to real users for testing purposes. Firebase requires test numbers to be fictional.

Specific Format: The formatting of the test phone numbers plays a crucial role in the authentication process.

Solution: How to Properly Format U.S. Test Phone Numbers

1. Use Fictional Test Numbers

Instead of using any existing phone numbers, embrace the use of fictional ones. One universally accepted method for US test numbers is to use numbers starting with the prefix 555. For example, you can use:

Valid Test Number: + 1 650-555-3434

2. Ensure Correct Length and Composition

It's important to ensure that the numbers you are using for testing are ten digits long and follow the North American Numbering Plan. Here's how you can structure your test numbers:

Country Code: Start with + 1 for US numbers.

Area Code: Use any valid area code, like 650.

Local Number: The remaining digits should follow the standard phone number format.

3. Avoid Using Recent Formats

The user noted that test numbers previously worked until about a month ago. This suggests that Firebase may have updated their requirements or tightened restrictions. Always keep your numbers compliant with the latest Firebase guidelines.

Final Thoughts

Hurdles in Firebase phone authentication can be resolved by adhering to the correct formatting and ensuring you're using fictional test numbers. By following these guidelines, you will not only prevent errors but also streamline your authentication process.

If you continue to run into issues, don't hesitate to reach out to the Firebase support team, as they may provide insights into any recent changes or additional restrictions.

Now you’re armed with the knowledge to tackle Firebase phone authentication errors related to US numbers with confidence. Make sure you keep your test numbers fictitious and formatted correctly!
