That doesn't necessarily mean the seatpost needs replacing. I assume you've already tried tightening the clamp bolt for the saddle rails?

The existing seatpost size (if the post hasn't been shortened) is embossed into the existing post just below the maximum limit indicator ring towards the bottom of the post.

It sounds like the issue is the clamp area where the rails are held on place. I agree - check that for toghtness and condition before deciding you need a new post.

The seatpost is an older one. Where u have the one bolt fasterner and the separate pieces
i did take off the seat last week and put grease all over the rails and the insides of the seat post clamps, i more less saturated it with grease
but still creaks when pedalling. I know its the seat area as i dont hear creaking when i stand.
its an Argon 18 seat on a ARgon 18 road bike

It's also possible that the noise is coming from where the saddle rails enter the saddle itself.

Leather saddles have a lot of places to creak.
