No. It may say '18k plated', but will never carry a hallmark or mark of fineness.
The hallmark for jewelry indicates the person who made the jewelry. Every designer has their own hallmark. You will often see numbers by a hallmark such as 925 which means it is sterling silver or 14k, 18k etc which indicate the amount of gold in the jewelry. Hope this helps.

You can determine if your ring is silver or white gold by looking for a hallmark on the inside of the band. Silver is usually stamped with "925" or "Sterling," while white gold is typically marked with "10K," "14K," or "18K." Additionally, white gold has a slightly yellowish tint compared to the brighter, whiter shine of silver.
"Marked Peru 925 and 18K" indicates that the piece is made of sterling silver (925) and 18-karat gold (18K). It suggests that the item is a combination of both metals, with the silver being at 92.5% purity and the gold at 75% purity.
the mark resembles the number 1 and an upside down V or A without the line across finishing the A.
