How to prove a Porsche's build date
States the production completion date. The cheapest real build date on this list for a Porsche - if you can receive post in North America.
Routes, best first
The manufacturer's own date-of-manufacture label

- Nothing but a torch and a phone camera.
States when the car was built. This is the date every import rule is measured from.
Limits and gaps
A JDM-market car normally has no date-bearing label at all. Its caution plate carries model code, chassis number, engine model and paint and trim codes - and no date.
NHTSA puts this first: the 25-year period runs from the date of manufacture, and the agency looks for that date on a label permanently affixed to the vehicle by its original manufacturer. Everything else on this site exists because that label is missing. Photograph the driver's door aperture, the passenger door aperture, the engine bay bulkhead and the centre pillars before you conclude there isn't one.

Porsche Production Specifications (PPS)
Build dateStates the production completion date. The cheapest real build date on this list for a Porsche - if you can receive post in North America.
- issuer
- Porsche Cars North America
- cost
- $150
- time
- 6-8 weeks
- you supply
- The Porsche VIN. No ownership proof, no inspection, no photographs.
States when the car was built. This is the date every import rule is measured from.
Limits and gaps
Ships only within the United States and Canada - a hard blocker if you are buying in Europe and want the document before the car moves. Engine and transmission numbers are no longer supplied, original Kardex records are not released, and prior-owner and warranty history are withheld.
This replaced the old Certificate of Authenticity, which cost $110 for 1948-79 cars and $95 for 1980-on. If a forum post tells you to order a 'Porsche COA', this is what it has become.

Classic Technical Certificate (CTC)
Build dateStates the Date of Production and verifies engine and transmission numbers against factory records. Overkill for an import date; excellent for a sale.
- issuer
- Certified Porsche Classic Partner (authorised dealer)
- cost
- From $500 plus local sales tax
- time
- Not published
- you supply
- The VIN and the physical car, for a 63-point inspection and photography.
States when the car was built. This is the date every import rule is measured from.
Limits and gaps
Requires the car in front of a dealer, so it cannot be obtained before purchase or while the car is on a ship.
If all you need is a build date, order the Production Specifications instead and keep the other $350.

Certificate of Conformity (CoC)
No date of manufactureProves nothing about age, and is actively misleading: a CoC issued today for a 1997 car is dated today.
- issuer
- The manufacturer
- cost
- Typically EUR 100-250 from the manufacturer
- time
- Weeks
- you supply
- The VIN.
Carries no date of manufacture. Useful for other things; useless for proving a car's age.
Limits and gaps
The CoC carries the VIN, type approval, dimensions, masses, engine, emissions, tyres, brakes and colour. The only date on it is its own date of issue.
US shipping guidance sometimes lists a certificate of conformity including the production date as acceptable. Read that clause carefully - the words doing the work are 'including the production date'. A bare CoC has no production date on it.

EU registration certificate (V5C, carte grise, Zulassungsbescheinigung, libretto)
No date of manufactureStates first registration, not manufacture. First registration is normally later than the build - sometimes by more than a year. That gap is the whole problem.

Carries no date of manufacture. Useful for other things; useless for proving a car's age.
Limits and gaps
Council Directive 1999/37/EC, Annex I, defines the harmonised codes. (B) is the date of first registration and (I) the date of the current registration. There is no harmonised code for date of manufacture anywhere in the annex.
Individual member states may add national fields the directive does not harmonise, so check your own document. But no EU-wide manufacture-date field exists.
