This appeal from an order suppressing evidence requires that we consider the degree to which police may rely on anonymous tips in forming the reasonable, articu-lable suspicions necessary to justify investigatory stops.
See Terry v. Ohio,
A'Des Moines, Iowa, police dispatcher at approximately 4 p.m. on August 1, 1985, was told by an anonymous caller that a man had just left the caller’s house with four ounces of heroin in a silver foreign Japanese-like car, Illinois license YFM 640, 1 headed toward 13th and College. The dispatcher checked the license number through the police computer system and learned that Illinois plate YFM 640 had been issued to a gray or silver Volkswagen, a vehicle similar in size and shape to many Japanese cars but of German origin. At the direction of a narcotics officer the dispatcher notified police patrolling in the relevant area to watch for and stop the above-described car.
About 8:45 p.m. that same day police spotted a silver Volkswagen bearing the Illinois plates in question being driven about eight blocks from the intersection mentioned by the anonymous caller. The officers checked to see that the vehicle was still wanted and then stopped it, finding it to be occupied by two men. While the officers were attempting to obtain identification from these men they observed possible drug paraphernalia and felt that the men were acting suspiciously. The officers ultimately found on the men and in the car two ounces of heroin, a small plastic baggy containing marijuana, and nearly $1,800 in cash. The men, Perry McBride and Roy Villanueva, were charged with possession with intent to distribute heroin. See 21 U.S.C. § 841(a)(1) (1982).
In pretrial motions, McBride and Villa-nueva asked that the items found by the police be suppressed from evidence on the ground that they were discovered through an unreasonable search and seizure — that is, one without just cause — in violation of McBride’s and Villanueva’s rights under the fourth amendment. The district court, in an opinion issued from the bench, agreed, concluding that the police had no basis for their actions other than the anonymous telephone tip and that such a tip, under
Adams v. Williams,
Although absent clear error we are bound by the district court’s findings of fact regarding the circumstances of McBride’s and Villanueva’s arrests, we may reverse if that court’s ultimate ruling on suppression reflects an erroneous view of the applicable law.

We note first that the anonymous caller’s tip suggested some basis for firsthand knowledge,
see generally Gates,
In addition, the caller’s information was corroborated in two respects. The dispatcher verified that Illinois license plates so numbered did exist and were assigned to a small silver foreign car, and the officers observed the described vehicle in the designated neighborhood.

As we have made clear even in cases involving the higher degree of reliability needed to establish probable cause, it is immaterial that the details corroborating an informant’s tip are as consistent with innocent conduct as with illegal activity.
United States v. Reivich,
The information on which the police acted here is similar to that held sufficient to give rise to a reasonable articulable suspicion in
McClinnhan,
where officers stopped a pedestrian based on an anonymous caller’s description and allegation that the man was carrying a gun in his briefcase. McBride and Villanueva make much of the fact that the informant here did not mention the physical characteristics of the man who was allegedly driving the silver car and did not mention a second man, but we do not believe these considerations undercut the reliability of the tip inasmuch as the caller gave a specific license number and alleged that the heroin was in the vehicle. In addition, the eight-block disparity between the intersection identified by the caller and the location where the vehicle was found is not greater than might reasonably be expected.
See United States v. Aldridge,
Finally, McBride and Villanueva point to the time gap of nearly five hours between the police dispatcher’s receipt of the tip and the stop of the silver Volkswagen. The inability of the officers to find the car near the identified area at the time of the tip to some degree vitiates that aspect of the corroboration (though we observe that the dispatcher testified that it might have been thirty minutes before the patrolling officers were actually in possession of the tip), and we certainly would consider the time lag a major problem had the police acted merely on a general description of a car rather than on a specific license number or had the car been sought in connection with a fast-breaking crime. Here, there is no question that the vehicle stopped was the vehicle police sought as the result of the tip.
We reiterate that our decision to uphold the investigatory stop by police in this instance is based on an individualized evaluation of the particular anonymous tip in the totality of the circumstances. We do not mean to suggest that tips less substantial in terms of the personal basis of the informant’s knowledge, the specificity of the information, and the nature and circumstances of the alleged illegal activity would satisfy the fourth amendment’s requirement of reasonable, articulable suspicion. We hold only that the tip in this case passes constitutional muster.
We reverse the order of suppression and remand to the district court for further proceedings.
Notes
. The transcript of the call apparently suggests that the license number given by the informant was YFAf 640, but the district court stated that it appeared that the dispatcher had understood the caller to say and had used "M.” Either way, we think it unlikely that error in one figure would affect our decision on reasonable suspicion.
See Wantland v. United States,
. McBride and Villanueva argue that the police decided to make the investigatory stop before verifying that the car sought could be found in the designated neighborhood. The record shows, however, that the information from the tip was transmitted only to officers patrolling in the general area of the intersection identified by the caller and that the officers who spotted the vehicle checked again with the narcotics division before making the stop.
