Offer Letter vs Appointment Letter in India: What Is the Difference?

Last updated: 8 October 2026 · By the Asuraa Team

Quick answer: An offer letter proposes a job and its broad terms before you join; an appointment letter formally appoints you and records detailed terms such as salary breakup, probation and notice period. Under the labour codes that took effect on 21 November 2025, the government says appointment letters are mandatory for all workers. Always check that your appointment letter matches the offer you accepted.

Key takeaways

An offer letter proposes the role, CTC, location and joining date and is accepted before you join.
An appointment letter is issued at or after joining and records detailed terms such as salary breakup, probation, notice period and confidentiality.
The government's 21 November 2025 release on the labour codes lists mandatory appointment letters for all workers.
Existing labour laws and rules continue during the transition while rules under the new codes are finalised, according to the same release.
If an appointment letter differs from the accepted offer, raise the mismatch in writing before signing and keep copies of both documents.

An offer letter and an appointment letter are two different documents in the Indian hiring process. The offer letter comes first and proposes the job; the appointment letter usually comes at or after joining and confirms your employment on detailed terms. Many freshers sign both without knowing which one actually governs their job, and that causes confusion later over notice periods, bonds and salary.

This is general information, not legal advice.

What is the difference between an offer letter and an appointment letter?

An offer letter is a proposal of employment that you accept before joining, while an appointment letter formally appoints you and sets out the detailed terms of your employment. The offer letter answers "would you like this job on these broad terms?"; the appointment letter answers "here are the rules of your employment from now on".

Point	Offer letter	Appointment letter
When issued	After selection, before joining	On joining day or soon after; sometimes after probation
Purpose	Proposes the role and invites acceptance	Confirms appointment and records full terms
Typical length	One to three pages	Several pages, often with annexures and policies
Salary detail	CTC, sometimes a short breakup	Detailed breakup and pay structure
Conditions	Subject to documents, background check, joining by a date	Probation, confirmation, notice, conduct, confidentiality, IP
Can it be withdrawn?	Companies sometimes revoke offers before joining	Ending employment then follows notice and termination terms
What you do	Sign and return acceptance	Sign a copy acknowledging the terms

Some companies combine the two into one long "offer cum appointment letter", especially for campus hires. Others issue only a short offer and rely on HR policies after joining.

What does an offer letter usually contain?

An offer letter usually contains the role, location, CTC, expected joining date and the conditions the offer depends on. Typical contents:

job title, grade or band, and work location
annual CTC, sometimes with an indicative breakup
joining date and the deadline for accepting
conditions such as clearing background verification, submitting documents or completing your degree
a brief mention of probation, notice period or service agreement, if any

Treat the conditions as seriously as the salary. Our checklist on what to check in an offer letter goes through each clause in detail. If an offer depends on clearing background verification, make sure the documents and dates on your resume match your certificates.

What does an appointment letter usually contain?

An appointment letter contains the full terms of employment you are bound by after joining. Expect:

designation, reporting manager and department
detailed salary breakup, including PF, gratuity and any variable pay
probation length and how confirmation happens
notice period, during and after probation
leave entitlement and working hours, or a reference to HR policy
confidentiality, intellectual property and conflict-of-interest clauses
any service agreement, training bond or clawback terms
rules on outside work, which matter if you plan side projects

Are appointment letters now mandatory in India?

The government says yes for workers covered by the new labour codes. Its Press Information Bureau release of 21 November 2025 announcing that the four labour codes had taken effect lists mandatory appointment letters for all workers, describing them as written proof meant to improve transparency and job security. The same release mentions appointment letters specifically for IT and ITES employees as part of their social security protections.

The release also notes that existing labour laws and rules continue during the transition while rules under the codes are finalised (PIB). In practice, if you have joined and received only an offer letter, it is reasonable to ask HR for a formal appointment letter.

Which letter is legally stronger?

Neither letter is "the contract" on its own; both are evidence of what you and the employer agreed, and the appointment letter usually records the more detailed terms. Once you have joined, the appointment letter and the policies it refers to typically govern day-to-day matters such as notice and probation.

How enforceable any single clause is, such as a bond or a restriction after you leave, depends on its wording and on Indian contract and labour law, not on which letter it appears in. If a clause worries you, ask for clarification in writing before signing and take legal advice for any dispute.

How should freshers from campus placements handle these letters?

Campus hires often receive an offer months before joining, and the appointment letter only on day one, so keep track of what was promised in between. A few practical habits help:

Save the original offer PDF and the acceptance email in one folder, along with any later emails about joining dates or location changes.
If your joining is delayed, ask HR to confirm in writing that the offer still stands on the same terms. Our guide to a delayed joining date explains what to ask.
On joining day, read the appointment letter before signing, even if HR is processing a large batch. Ask for a copy if you need time.
Note the probation length and confirmation process. Our explainer on the probation period in India covers what usually changes after confirmation.

Students placed through campus drives sometimes assume the college placement cell will handle discrepancies. It usually will not after you join, so raise issues with HR directly.

What should you check when moving from offer to appointment letter?

Check that the appointment letter matches what the offer letter promised, line by line. Follow these steps:

Lay the two documents side by side. Compare designation, location, CTC and joining date.
Compare the salary breakup. Make sure the CTC matches and the fixed portion has not shrunk in favour of variable pay. Our guide to CTC vs in-hand salary helps you convert both into take-home pay.
Read the notice period and probation clauses. These often appear only in the appointment letter.
Look for new clauses. Bonds, clawbacks, non-compete language or relocation rules that were not in the offer deserve questions.
Check PF details. Confirm how PF is calculated; according to EPFO, employees and employers each contribute 12% of basic wages plus DA, with a Rs 15,000 statutory ceiling that some employers use as the base.
Raise mismatches in writing before you sign, and keep HR's reply.
Keep signed copies of both letters.

What do most guides on offer letters and appointment letters get wrong?

Most guides say the offer letter "has no legal value", which is misleading. A signed offer and acceptance record commitments by both sides, and freshers whose offers are revoked often rely on these documents when they complain or negotiate compensation. Our guide on what to do if a job offer is revoked covers the options.

A second error is assuming the appointment letter can quietly change anything. If the appointment letter offers worse terms than the offer you accepted, you are entitled to ask why before signing. Many differences turn out to be formatting or policy references; some are real changes you should negotiate.

What if you never receive an appointment letter?

Ask for it in writing, politely, within your first few weeks. A short email to HR stating your joining date and requesting a copy of your appointment letter and current salary structure is enough. Until then, keep your offer letter, acceptance email, first payslips and PF passbook as proof of employment. You can activate your UAN and download the passbook from the EPFO Member Portal.

Before accepting any offer, also confirm it is genuine. Our guide on how to check if an offer letter is fake lists the warning signs.

Do relieving and experience letters relate to these documents?

Yes, they bookend your employment. The offer and appointment letters start it; the relieving letter and experience letter close it and are often requested by your next employer. Ask for both when you resign, and keep them with your offer and appointment letters.

FAQ

Is an offer letter the same as an appointment letter?

No. An offer letter is a proposal you accept before joining, covering the role, CTC, location and joining date. An appointment letter is issued at or after joining and records the detailed terms of your employment, such as salary structure, probation, notice period and confidentiality. Some companies combine both into a single offer cum appointment letter.

Is an appointment letter mandatory in India?

The government says so for workers covered by the new labour codes. Its Press Information Bureau release of 21 November 2025, announcing that the four labour codes had taken effect, lists mandatory appointment letters for all workers. Existing rules continue during the transition, so if you have not received one after joining, ask HR in writing.

Can an offer letter be cancelled after I accept it?

Companies do sometimes revoke offers before joining, for reasons such as failed background verification or changed business needs. Your signed offer and acceptance are evidence of what was agreed, which helps when you raise a complaint or negotiate compensation. Keep all emails and documents, and seek legal advice if the loss is significant.

Which letter decides my notice period?

Usually the appointment letter, together with the HR policies it refers to, because it records the detailed terms you work under after joining. Offer letters sometimes mention a notice period too. If the two documents differ, ask HR to clarify in writing which applies before you sign the appointment letter.

What should I do if my appointment letter shows a lower salary than my offer?

Do not sign immediately. Compare the CTC and the breakup with your offer letter, then email HR describing the difference and asking for a correction or explanation. Sometimes the change is only a restructured breakup with the same CTC; if fixed pay has actually fallen, you are entitled to negotiate before accepting.

Final thoughts

The offer letter gets you in the door; the appointment letter defines the job you actually signed up for. Read both, match them line by line, and ask questions in writing before you sign. If a clause still confuses you, a quick 1:1 session with an Asuraa mentor can help you decide what to ask HR.
