Changing your address sounds like one task and is really thirty: the post office, your bank, insurance, subscriptions, the DMV, and every account tied to where the mail lands. Address change services promise to shrink that list, but they range from a single free USPS form to paid concierge tools and mail forwarding. Here is what each one actually does, so you update everything without paying for work you can do free.
File the official USPS change to forward your mail, then work through the MovePlan tracker or checklist so every bank, insurer, and subscription gets your new address. Paid services like Updater and DoNotPay can save time, but be careful not to pay a premium for the free USPS step.
