'Perdón' means 'sorry, pardon me, excuse me', but the most common is 'Sorry!'. 'Disculpe' is more formal and polite, like 'Excuse me!'

They both mean almost the same "Disculpe" is a formal way to say excuse me.. to your professors, old people, people you barely know o people you dont know at all. "Disculpame" is more informal that the first one.. to your friends, people of your same age etc.. "Perdón " is the almost same as pardon but not in all contexts you can use it, when u didnt hear something, u say: Perdón, qué dijo? but thats too polite. perdón is also deeper than disculpe or disculpa. if u hurt to someone u ask for their forgive by saying : Perdón Perdóname Perdóname is more informal: To ur family, to ur god, to someone who you love u may hear perdóname in love songs. Sorry for my english i still learning it

Perdón and disculpe it's the same mean, but Perdón is more formal than disculpe.
