  Trunk roads in Tanzania were marked by numbers following the two-tier number system with prefixes A- and B-, as is practiced in the rest of East Africa. Following is the list of Tanzanian trunk roads. Meanwhile Tanzania has introduced a numbering system for trunk roads using numbers starting with "T" but so far the "A" designations are visible if at all.
