Wapito accepts international format, bare digits, both user suffixes, the group and channel suffixes and the linked-identity suffix, and normalises internally.

Take it from the create response or from the group list, keep it as a string, and never reconstruct it - it is longer than a 64-bit integer, so any numeric handling will corrupt it.","Can I build a group id this way?",{"a":27,"q":28},"A linked identity has its own suffix and is not derived from a phone number at all, so this tool cannot convert between them. Resolving one to a number is an API call against a real session, because only the network knows the mapping, and sometimes the answer is that there is not one.","What about linked identities?","phone numbers to WhatsApp ids","Paste a phone number in any format and this converter shows the WhatsApp ids - the JIDs - it corresponds to, along with the group and channel address shapes for comparison. WhatsApp inherited its addressing from an older messaging protocol, so everything you can message has an address that looks like an email: an identifier, an at sign, and a server part that says what kind of thing it is. Users have one suffix, groups another, channels a third, and linked identities a fourth. Two different user suffixes exist because the web and mobile stacks grew up separately, which is why different libraries hand you different-looking strings for the same person. This tool shows the normalisation Wapito performs, so you can see what your input becomes. The conversion itself is simple - strip everything that is not a digit, drop the leading zero, add the country code - but the failure mode is subtle: a national-format number with the trunk prefix left on is a valid-looking address for a different number entirely.\n\nFor a person, the address is the number in international digits followed by the s.whatsapp.net suffix. That is the canonical form, the one the protocol uses internally and the one Wapito writes into every response and every webhook, so the id you get back from a send is the id you will see on the reply. The c.us form with the same digits is the older spelling that the web client and the libraries built on top of it made popular; it names the same account, and Wapito accepts it on input for that reason, but you will never see it in output. If your code compares ids, compare digits or normalise both sides first, because two strings that name the same person are not equal as strings.\n\nThe other suffixes are not derived from a phone number and cannot be produced by this page. A group id is a long number assigned by WhatsApp when the group is created, followed by the g.us suffix, and the only way to know it is to read it from the create response or the group list. A channel - what WhatsApp calls a newsletter in the protocol - has its own numeric id and its own suffix, and again comes from the API rather than from anything you can type. A linked identity, the lid suffix, is the one people trip over most: it is an opaque id WhatsApp now uses in place of a phone number in some contexts, notably in groups and for accounts that have chosen to hide their number, and it maps to a phone number only if the network is willing to tell you. Resolving one is an API call against a real session, and sometimes the answer is that no mapping is available.\n\nThe practical rule that falls out of all this is to store ids as strings and never as numbers. A group id is longer than the largest integer a floating-point number can hold exactly, so any spreadsheet, JavaScript runtime or database column that treats it as a number will quietly round the last digits and hand you an address that belongs to nobody. Keep the whole string, suffix included, and pass it back unchanged. When you do have a phone number and need the address, use the digits this tool produces or simply send the international number: Wapito accepts either and normalises it the same way. The endpoint linked below is the one that resolves the mapping this page cannot compute, from a linked identity back to a phone.","Phone to JID Converter",{"glossary":33,"hub":43,"operation":18,"pillar":9,"tools":44},[34,37,40],{"title":35,"url":36},"LID","\u002Fglossary\u002Flid\u002F",{"title":38,"url":39},"JID","\u002Fglossary\u002Fjid\u002F",{"title":41,"url":42},"Group admin","\u002Fglossary\u002Fgroup-admin\u002F","\u002Ftools\u002F",[45,48,51,54,57,60,63],{"title":46,"url":47},"WhatsApp Number Checker","\u002Ftools\u002Fwhatsapp-number-checker\u002F",{"title":49,"url":50},"WhatsApp Link Generator","\u002Ftools\u002Fwhatsapp-link-generator\u002F",{"title":52,"url":53},"WhatsApp QR Code Generator","\u002Ftools\u002Fwhatsapp-qr-code-generator\u002F",{"title":55,"url":56},"WhatsApp Text Formatter","\u002Ftools\u002Fwhatsapp-text-formatter\u002F",{"title":58,"url":59},"JSON String Escaper","\u002Ftools\u002Fjson-string-escaper\u002F",{"title":61,"url":62},"Group Invite Link Parser","\u002Ftools\u002Fgroup-invite-link-parser\u002F",{"title":64,"url":65},"Webhook Payload Inspector","\u002Ftools\u002Fwebhook-payload-inspector\u002F",{"breadcrumb":67,"canonical":75,"description":76,"h1":77,"lastmod":78,"title":79},[68,71,73],{"name":69,"url":70},"Home","\u002F",{"name":72,"url":43},"Tools",{"name":31,"url":74},"\u002Ftools\u002Fphone-to-jid-converter\u002F","https:\u002F\u002Fwapito.com\u002Ftools\u002Fphone-to-jid-converter\u002F","Free Phone to JID Converter: phone numbers to WhatsApp ids.
