RCW 47.42.130Permit identification number.Every permit issued by the department shall be assigned a separate identification number, and each permittee shall fasten to each sign a weatherproof label, not larger than twenty-eight square inches, that shall be furnished by the department and on which shall be plainly visible the permit number. The permittee shall also place his or her name in a conspicuous position on the front or back of each sign. The failure of a sign to have such a label affixed to it is prima facie evidence that it is not in compliance with the provisions of this chapter.[ 2013 c 312 s 3; 1999 c 276 s 2; 1984 c 7 s 233; 1961 c 96 s 13.]
