Quackr runs two products side by side. The free tier lists shared numbers whose inboxes are visible to anyone, rotated roughly monthly; according to its FAQ these are VoIP numbers. The paid tier rents a dedicated number for a week, a month, six months or a year, and the FAQ describes those as non-VoIP. It covers 24 countries, accepts PayPal, cards and crypto, and offers an API.
Its refund policy is written clearly: you can ask for a fix or replacement within 48 hours, a full refund follows two failed replacements, and a number that has already received a code counts as used.
The free inboxes are the part to be careful with. Anyone can read a public inbox, so a code sent there can be used by a stranger. For accounts you care about, a private number is the only safe option.
PhoneBorn only sells private numbers: real mobile numbers in 200 countries that stay assigned to one customer while the plan is active, with SMS and calls both ways. For one-off codes, OTP numbers refund automatically if nothing arrives.
