Offer Letter vs Appointment Letter: What Is the Difference?

Landing a job after months of interviews or exams feels great. Then the emails and documents start arriving and two names keep coming up: offer letter and appointment letter. A lot of students treat them as the same thing. They are not.

The offer letter arrives first. The company is basically telling you they want you for the role. Usually, it talks about the designation, the salary or CTC they have in mind, date of joining and place of work. It may also include some conditions like submitting documents or passing a background check. At this stage you are still a candidate. The letter is an invitation, not the final confirmation.

Once you accept the offer and finish the formalities, the appointment letter comes. This one is more serious. It confirms that you are now an employee. The language becomes detailed. You will find the exact salary break-up, your reporting manager or department, the probation period, notice period, leave rules and the company’s policies. Both sides normally sign it. From that point the document acts as the main reference for your employment terms.

Timing makes the difference clear. The offer letter is sent after selection but before you join. The appointment letter is given on the day of joining or around that time, after the offer has been accepted and the checks are done.

The legal weight is also different. An offer letter is mainly a proposal. Companies can sometimes change or withdraw it if the conditions are not met. The appointment letter, once signed, carries more binding force under Indian employment practices. If any question later arises about salary, notice or service conditions, this is the paper people look at.

In private companies the offer letter often helps candidates resign from their current job or plan the move. In government and public sector jobs the appointment letter holds special importance. It formally appoints the person and sets out the service rules that will apply.

For students coming out of campus placements or clearing competitive exams, the practical takeaway is simple. Celebrate the offer letter, but treat the appointment letter as the document you must keep carefully. Check that the figures and dates match what was discussed. Keep both soft and hard copies safely.

These two letters simply mark different stages. One shows the company is interested. The other says you have joined. Knowing the difference makes the first few weeks of a new job a little less confusing.
