At times it may be necessary to determine the carrier for a number. If messages are undeliverable, use this tool to look up the carrier to see if other numbers are affected as well; meaning the issue may be at the carrier level. Numbers can be reviewed via Bulk Upload option or Copy/Paste.
Note: Each lookup uses 1 credit.
From the Tools main menu, click Carrier Lookup.
