Hey @Cole_Canning , thanks for reaching out and providing the details here!

It looks like the library we use internally just needs to be updated - it’s treating 686 area code US numbers as invalid, as I believe that area code was added back in 2024.

We’ll get that fixed and follow up here once that’s done. Apologies for any inconvenience there!

Thank you, look forward to seeing it fixed! Any idea on timeline? We thinking days, weeks, or months?

Thanks

Cole

We don’t have a specific ETA to share at the moment, but it should be closer to days than weeks! Will keep you updated here.

Hey @Cole_Canning , this should be fixed now - please let us know if you still get an error creating users with a US 686 area code phone number!

I was able to create a user through the dashboard the 686 area code, thank you!
