Glossary: private and virtual phone number terms, explained

Below is a one-line definition for each term, followed by a link to the full explainer. Each term page goes deeper with examples, trade-offs, and how it applies to a real long-term local number you keep — not a temporary or recycled line.

The core terms

• No-KYC phone number — a line you activate without submitting any identity document, name, address, or payment card; the provider never runs a Know Your Customer check on you.
• Virtual phone number — a real, dialable number delivered over the internet to a browser or app instead of a physical SIM, so it works on any device with no hardware.
• VoIP vs non-VoIP number — VoIP numbers ride internet protocols and are often flagged by apps; non-VoIP (mobile/landline) numbers sit inside a country's national numbering plan and pass more checks.
• eSIM vs virtual number — an eSIM is a downloadable SIM profile tied to a device and a data plan; a virtual number is a browser-based line with no SIM, no device lock, and no eSIM slot needed.
• DID number — a Direct Inward Dialing number: a real, individually routable telephone number that lets calls and texts reach you directly without going through a switchboard.

These distinctions matter because the label on a number decides whether apps, banks, and exchanges accept it, and whether the number is genuinely yours to keep. A real DID mobile or landline allocated inside a national numbering plan behaves like any carrier line, so it passes most verification flows; a recycled VoIP gateway number is widely flagged and may already be tied to someone else's old accounts.

The other distinction is permanence. A temporary or burner number is shared, recycled, and lost within minutes or days — useful for a throwaway one-time code, useless for a line you want to receive calls on next year. A real long-term number stays yours as long as you keep the subscription active. See long-term vs temporary numbers for the full comparison.

Finally, no-KYC is about who knows the number is yours. With crypto-only billing and no identity on file, the only thing observed is an on-chain payment — not your name. Read how to keep your phone number private.

A PrivacyNumber line is, in glossary terms, a real long-term local DID that is virtual (browser-delivered, no SIM), non-VoIP in character because it is allocated inside each country's national numbering plan, and no-KYC because no identity is ever required. It is not an eSIM and not a physical SIM — see eSIM vs virtual number.

Concretely, that means:

• A French line is a real +33 6/7 mobile or a regional landline; a US line carries a real area code like 212 or 415.
• It does two-way HD calls, sends and receives SMS/MMS, and includes voicemail with transcription and translation, plus optional AI auto-pickup.
• You activate it in under 60 seconds after a crypto payment confirms, across 47 countries, and you keep it for as long as you keep paying.

For how the money side stays private, see pay with Monero or pay with Bitcoin.

Honest note: most consumer apps and one-time-code flows accept these lines, but some VoIP-aware fintech apps and some bank or government portals run identity checks beyond SMS that no virtual provider can bypass. If a service rejects a freshly activated line, support swaps it to a different carrier range free within 7 days. Questions? Use the contact form.
