FAQ

Frequently asked questions

Straight answers about your list, payment and results

Ask us in the chat
Which file formats can I upload?

A .txt or .csv file, up to 40 MB and 2,000,000 numbers per order, one number per line. In a CSV the first cell that holds a phone number is used, so a header row or other columns are simply skipped

How is the price calculated?

Unique numbers of the order's country × the price of the check. Duplicates, lines that are not phone numbers and numbers from other countries are removed first and not charged. For example 10,000 numbers with iMessage Checker at €120 per 1,000,000 cost €1.20. Your account shows the exact amount before you place the order

How do I pay?

In crypto: USDT (TRC20, BEP20, ERC20), ETH (ERC20), SOL and BTC. The amount is added to your EUR balance once the payment is confirmed on the network. The minimum top-up is €10. What a check costs depends on the check and the size of your list, and what you do not spend stays on your balance
