A birthday invitation message should name the person being celebrated, state the date, time and venue, and explain how guests should reply. If you are a planner writing for a client, confirm those details and the invitation's guest allowance before sending. The samples below are original wording you can copy and adapt for WhatsApp or SMS.
Replace every bracket, check the calendar date against the day of the week if you include one, and ask the client to approve the final version.
A simple birthday invitation
You are invited to celebrate [name]'s birthday on [date] at [time]. Join us at [venue and address] for [brief description]. Please confirm by [reply deadline] using [reply link or contact]. We look forward to celebrating with you.
This version works where the tone should be friendly and clear. Keep the essential details in the message even if you also attach a designed invitation image. A guest should not need to zoom into artwork to find the address.
A milestone birthday invitation
Please join us as we celebrate [name] at [age or milestone].
Date: [date]
Time: [time]
Venue: [name and address]
Dress code: [only if agreed]
Kindly confirm your attendance by [deadline] at [reply route]. Your invitation covers [named guests or agreed number].
Confirm that the client wants the age published. The planner should not infer it from a conversation or add it simply because a milestone template has a space for it.
A children's party invitation
[Child's first name] is celebrating a birthday, and [invited child's name] is invited.
Join us on [date], from [start time] to [finish time], at [venue and address]. Please reply to [parent or organiser contact] by [deadline]. [State the agreed arrangement for accompanying adults and siblings.] Please contact us privately about any arrangements we should discuss.
For a children's event, direct the message to the responsible adult. Confirm the accompanying-adult and sibling policy with the host rather than leaving the family to guess. Keep children's personal information out of broad public announcements.
A surprise party invitation
We are planning a surprise birthday celebration for [name]. Please arrive at [guest arrival time] on [date] at [venue]. The celebrant is expected at [time]. Please keep the details private and confirm with [organiser] by [deadline]. Contact [person] if you need help finding the entrance.
Give guests a realistic arrival instruction and one person to contact. Do not put the celebrant into a reminder group or send them a general guest broadcast by mistake.
A short SMS invitation
Celebrate [name]'s birthday: [date], [time], [venue]. Please RSVP by [deadline] to [contact or short reply link]. Invitation for [guest allowance].
Keep the address or a usable route to it. If the message becomes long, shorten decorative language before removing the reply deadline or location. Message length and delivery costs depend on the sending route; check the actual send rather than assuming one sample equals one billed SMS.
Clarify access without sounding hostile
Where the host has agreed restricted entry, add a calm instruction:
Please bring your invitation or access pass. Contact [organiser] before [date] if the named guests need changing.
An invitation message and an access record serve different purposes. Forwarding the wording should not be treated as approval for extra guests. Agree the exception process with the host and gate lead.
Use the guest-list template for the same name, household and reply structure, adapting the event labels to the birthday. Send RSVP reminders only to unresolved records.
Comtev helps planners collect names, send invitations and QR access passes, and scan guests in. See the workflow if the client's birthday guest list is arriving in several different chats. Sends have wholesale usage costs; the planner sets their own client price.
