Appointment Reminder SMS Template for Hospitals & Clinics

A ready-to-adapt SMS message for hospitals and clinics, with placeholders, sample values and compliance notes.

When to Send This Message

Send the day before (and optionally two hours before) to reduce no-shows. For hospitals and clinics, this is one of the everyday messages that keeps patients informed without a phone call. Most businesses send it automatically from their software, so the timing is consistent.

After the visit, clear reminders and reports keep them coming back and reduce missed appointments.

The SMS Template

India (DLT format)

Header: [6-character header]-S · Category: Service Implicit

Reminder: {#var#}, you have an appointment with {#var#} tomorrow, {#var#}, at {#var#} at [Business Name]. Please arrive 15 minutes early for registration.

International (plain text)

Reminder: {patient}, you have an appointment with {doctor} tomorrow, {date}, at {time} at [Business Name]. Please arrive 15 minutes early for registration.

Example with sample values

Reminder: Ravi, you have an appointment with Dr. Sharma tomorrow, 14 Oct, at 10:30 AM at [Business Name]. Please arrive 15 minutes early for registration.

With these sample values the message is 156 characters in the standard GSM-7 character set, which is 1 SMS part (square brackets count as two characters each). Long links or local-language (Unicode) text increase the count, as Unicode SMS allow 70 characters per single part.

Replace [Business Name] with your registered brand name. Links shown use example.com as a placeholder; use your own domain.

Placeholders and Sample Values

Placeholder	Meaning	Sample value
{#var#}	Patient	Ravi
{#var#}	Doctor	Dr. Sharma
{#var#}	Date	14 Oct
{#var#}	Time	10:30 AM

Filling in each placeholder

Patient (sample: Ravi): Use the first name or the salutation the customer gave you; fall back to a neutral greeting if the field is empty.
Doctor (sample: Dr. Sharma): Keep the value short and specific; test the longest realistic value to check the message still reads well.
Date (sample: 14 Oct): Write dates in an unambiguous form such as 14 Oct or 14 Oct 2026; avoid formats like 10/11 that customers read differently.
Time (sample: 10:30 AM): Give times with AM/PM or a clear range, and the time zone if the customer may be in another country.

This template has 4 placeholders and a body of 155 characters before values are filled in. Shorter messages cost less and are more likely to be read in full; aim to keep the filled-in message within one or two SMS parts.

Category and Approval

In India this type of message is usually registered as Service Implicit: it relates to an existing transaction or relationship and can be delivered to numbers on the DND registry. It must not contain promotional content.

Compliance Checklist

Each {#var#} holds only the kind of value it was registered for; most platforms limit each variable to 30 characters.
Any link uses a domain whitelisted for your header, as TRAI requires for URLs in commercial SMS.
The brand name in the message matches your registered business or header.

Rules to keep in mind for Hospitals & Clinics

Medical advertising in India must follow the National Medical Commission's professional conduct rules for doctors, the Drugs and Magic Remedies (Objectionable Advertisements) Act and ASCI guidelines, so we avoid claims of guaranteed cures and before/after promises. Patient data is sensitive personal data and should be handled under the Digital Personal Data Protection Act, 2023.

General guidance, not legal advice. Rules change, so confirm current requirements before launch. See our SMS compliance guide for India.

Tips for Better Results

Keep one purpose per message; if you need to send a reminder and a document, the reminder should still make sense on its own.
Use the customer's name and a reference number so the message is easy to trust and to search for later.
