Adding contact center address book entry via API prepends "+1" to the phone number

Previously, when I added numbers to an address book via the API, it did not prepend “+1” to the number. I can still manually add entries via the web portal, and it does not prepend “+1”, but I would like to use the API! Any idea why it could be doing that? I am using PowerShell, and here is a code sample:

$body = @{
“display_name” = “Josh”
“phone_numbers” = @(“1234”)
} | ConvertTo-Json

Invoke-RestMethod -Uri “$baseUri/v2/contact_center/address_books/$addressBookId/contacts” -Method POST -Headers @{ “Authorization” = “Bearer $accessToken”; “Content-Type” = “application/json” } -Body $body

The resulting entry has the phone number “+11234”

Hi @Josh11
Thanks for reaching out to us and welcome to the Zoom Developer Forum!
Were you able to add numbers without pretending the +1 to the number?
Is having this +1 blocking your integration or breaking it in any way? or why would you like to avoid this?
