Check a list of numbers
Upload an .xlsx, .xls or .csv file of US phone numbers. The column named “phone” is used automatically, otherwise the column with the most valid numbers.
File format
- One number per row, header row on top. Max 20 MB.
-
Name the phone column
phone— a header containing number, mobile, cell, tel, contact or msisdn also works. Any other columns are ignored and are not returned in the export. -
10-digit US numbers only.
(925) 404-7311,+1 415 555 0142and2065550119are all accepted; anything else is reported as invalid rather than checked. -
Demo files use the
555exchange, so they run end to end without looking up a real subscriber. Remember each row is one billable API lookup — the 100,000-row file is a load test, not a freebie.
