No. A deed's legal description and its parcel identification number serve different purposes, and only the legal description defines the land being conveyed.
The Legal Description
The legal description identifies the land precisely, usually by lot, block, and subdivision with a reference to the recorded plat, or by metes and bounds measured from a fixed point. It is normally carried forward word for word from the prior recorded deed, because a small change can describe a different piece of land.
The Parcel ID Number
The parcel identification number is assigned by the county property appraiser for tax purposes. Florida's statutory deed form includes a space for it, to be filled in when available (section 689.02(2)). The statute states that the parcel number is not part of the legal description and cannot be used as a substitute for it.
When the Number Is Wrong
A missing or incorrect parcel identification number does not affect a deed's validity or whether it can be recorded (section 689.02(2)). An error in the legal description is more serious. It can leave title unclear and is usually fixed with a corrective deed. A street address is not a legal description either, even though it often appears on the deed for reference.
