Clаiming that a warrantless inspection of an automobile’s confidential identification number was an illegal search, Armón Doss Powers appeals his convictiоn of violating the Dyer Act [18 U.S.C. § 2312]. We hold that when there is a legitimate reason to identify a motor vehicle, inspection of its confidential number is not an unreasonable search, and we affirm.
On the night of November 4, 1969, Powers was arrested for speeding and driving while his license was revoked. Because Powers was jailed, the pоlice directed a garageman to remove and hold his car. At the time of the arrest, the state highway patrolman noticed that the vehicle identificаtion number plate was missing from the door post. He promptly sent out a tracer on the license plate number and called for assistance in identifying the vehicle. The next day, the arresting officer, along with the special agents he requested, inspected the automobile without a search warrant for the sole purpose of identifying it. They opened the left door of the car and confirmed the absence of the vehicle identification plate. Two оf the officers got beneath the car and recorded the confidential number which is impressed in a remote and barely accessible place. Thе number disclosed the car was stolen. At his trial, Powers contended, as he does on appeal, that the confidential number was inadmissible because the officers obtained it in violation of his Fourth Amendment rights.
Courts differ about the legality of obtaining a motor vehicle’s identification number without a search warrant. Some hаve held a warrantless search to be illegal — and the number inadmissible in evidence — when the vehicle’s inspection was not incident to a lawful arrest. United Statеs v. Nikrasch,
Davis v. Mississippi,
The Fourth Amendment, as the Court has emphasized, was adopted to protect the right to be free from unreasonable searches, аnd the “specific content and incidents of this right must be shaped by the context in which it is asserted.” Terry v. Ohio,
The mobility of motor vehicles causes them to be attractive to criminals in two respects. They are easily and frequently stolen; and, whether stolen or not, they are convenient — sometimes indispensable — instruments of crime. Because cars are mobile, it is often impractical for police officers to secure warrants to search them, and the Court, recognizing this difficulty, has long distinguished the search of automobiles from the search of buildings. Carroll v. United States,
Inspection of a car’s identification number differs from a search of a vehicle and seizure of its contents in one important aspect. The occupants of the car cannot harbor an expectation of privacy concerning the identification of the vehicle. Thе state requires manufacturers to identify vehicles by affixing identification numbers which are also recorded in registries where the police and any interested рerson may inspect them.

Since identification numbers are, at the least, quasi-public information, a search of that part of the car displaying the number is but а minimal invasion of a person’s privacy. A police officer, therefore, should be freer to inspect the numbers without a warrant than he is to search а car for purely private property. Because of the car’s mo

bility, he may have little opportunity to do so if' he must first secure a warrant or havе probable cause for a search or arrest. Nevertheless, the legality of the search cannot be predicated on the “inarticulate hunches” or subjective “good faith” of the officer. Terry v. Ohio,
“[W]ould the facts available to the officer at the moment of the seizure or the search ‘warrant a man of reasonable caution in the belief’ that the action taken was appropriаte ?”
This standard can be met, we conclude, when the officer has a legitimate ground for checking the identification number. Cf. Cotton v. United States,
The officers became suspicious about the ownership of the car Powers had been driving because the identification number was missing from the dоor post. Quite reasonably this fact alerted the police to the need for further investigation, and it alone furnished a legitimate reason for cheсking the confidential number. We need not, therefore, describe other circumstances that would justify a search for an identification number. Also, since the offiсers did not detain Powers to conduct their search, we have no occasion to determine at what point a search for identification numbers would become unreasonable because of unlawful detention or harassment of the vehicle’s occupants, cf. Davis v. Mississippi,
We find no merit in Powers’ other аssignments of error. The judgment is affirmed.
Notes
. For example, the registration of motor vehicles is mandatory both in New York, the state in which the vehicle was stolen, N. Y. Vehicle and Traffic Law § 401 (McKinney’s Consol.Laws, c. 71, 1970), and North Carolina, the state in which Powers was apprehended, N.C.Gen.Stat. Ann. § 20-50 (1965).
