Property is often numbered twice, firstly to show which real estate lot it stands in, and then to distinguish where it is on that lot. Thus 154/7-10 Thanon Rajdamnoen means the building is on lot 154 and occupies numbers 7-10. "Thanon" means "road". Also, in large cities a minor road running off a major road is often numbered as a soi ("lane" or "alley", though it may be a sizeable thoroughfare), rather than given its own street name. Thanon Sukhumvit for example has minor roads numbered Soi 1 to Soi 103, with odd numbers on one side of the road and even on the other; so a Thanon Sukhumvit address could read something like 27/9-11 Soi 15 Thanon Sukhumvit, which would mean the property occupies numbers 9-11 on lot 27 on minor road number 15 running off Thanon Sukhumvit
