Good to know

  • The registered check may keep only the numbers of the country that appears most in your file. Numbers from other countries are removed at quote time and not charged.
  • Avatar links are signed and open directly while the order results are retained.
  • Gender and age are read from the avatar by AI and are for reference.

How orders work

  • Number format

    A UTF-8 TXT or CSV file with one column and no header, one international number with its country code per line (a leading + is fine). Up to 100 MB per file, or paste the numbers directly.

  • Billing

    The quote counts the numbers left after removing duplicates and invalid entries; invalid numbers are not charged. The quote is reserved when you order, and once the order finishes you pay for the numbers actually processed. The rest goes back to your balance.

  • Result files

    Successful numbers come in a CSV file and the others in a TXT file. Large orders are delivered in batches, so you can download finished parts while the order runs. A number in the unsuccessful file may simply not have been checked successfully this time; it is not proof the number is unregistered.

  • Countries and regions

    International numbers with a country code are supported, except numbers from mainland China (+86).
