5. NOTAM Service
5.1 NOTAM Publication (Postal Distribution)
5.1.1 NOTAM publication distribution, by means of the Notices to Airmen publication, is in booklet form which contains a recapitulation of pertinent or permanent information of concern to airspace, facilities, services, and procedures which are of interest to both international and domestic civil aviation users. The information contained will eventually be published in either the U.S. AIP or in other publications for domestic use, as applicable. The Notices to Airmen publication will also contain information regarding temporary changes or un-scheduled interruptions to flight procedures and navigational aids or airport services, the duration of which is expected to last seven or more days. Distribution of the Notices to Airmen publication parallels NOTAM Class I and AIP distribution.
5.2 NOTAM Class I (Telecommunication Dis-tribution)
5.2.1 NOTAM Class I distribution is used mainly for the notification of temporary information of timely significance such as unforeseen changes in services, facilities, airspace utilization, or any other emergen-cy.

NOTAMs are given selected distribu-tion to adjacent or appropriate International NOTAM Offices which require their exchange.
5.2.1.3 International Airspace NOTAM. NOTAM containing permanent changes.en route airway structure/aeronautical service and information of a general nature. NOTAMs are given selected distribution to adjacent or appropriate International NOTAM Offices which require their exchange.

5.2.1.5 Domestic NOTAM. NOTAM containing information of concern to aircraft other than those engaged in international civil aviation. Distribution is to local or national users only. (See ENR 1.10.)
5.2.2 Each NOTAM is assigned a four digit serial number which is followed by the location indicator for which the series is applicable. The serial numbers start with number 0001 at 0000 UTC on 1 July of each year. Each serial number is preceded by a letter:
