Can I renew my 15-year-old lost expired passport without mentioning?
You know, there are different laws and bureaucratic procedures for different countries. I dont know where you are, but in the US you cant renew a passport that was ISSUED more than 15 years ago, or which you no longer possess. Youd have to apply for a passport as though youd never previously had one, using a DS-11 and making your application in person.
