When you change your name, you are responsible for notifying all relevant organizations, including government bodies (Passport, Tax, Transport), financial institutions (banks, insurers), employers, medical providers, and utility companies; the official name change certificate or deed poll links your old and new names, but these entities don't get automatically updated. Only specific government systems (like police records) might get automated updates, but generally, it's a manual process of informing everyone you have an account with.
Financial institutions
Notify your bank, credit union, credit card companies, mortgage lender, and any other financial institutions of your name change. You'll need to update your account information and ensure that your new name matches the name on your ID.
The legal change of name process is managed by the Registry of Births, Deaths & Marriages in your state or territory.
Who you need to tell. When you change your name, you must tell everyone who holds a record of your details that you have changed your name. If you deliberately fail to do so, you may be committing fraud.
Most name change orders are public records, which means anyone can access the information through the court system and link your new name with your former name. If you want your name change to be confidential, you have to ask the court to seal the court record for a good reason.

There isn't one single "rarest" last name globally, as rarity depends on location and historical records, but extremely rare ones have only a handful of bearers, like some listed by Findmypast (e.g., Twelvetrees in 1901 Britain) or names with <100 people in the US, such as Villalva. Names become rare due to migration, extinction, or being tied to unique local landmarks or events, with some becoming "endangered" (fewer than 50 bearers in England/Wales), like Pober or Mirren.
Con: It's not free
It needs to get notarized. If your name change is the result of a divorce or a marriage, you may need additional documentation. It's not prohibitively expensive — court fees may be a few hundred dollars — but it does cost money. This is only something you want to do if you're serious about it.
A number of federal and state government agencies should be notified when you're moving, including the Internal Revenue Service (IRS) and the Social Security Administration (SSA). The IRS offers the convenience of updating your address electronically through Form 8822.

While changing your name won't directly cause you to lose followers, it can have an indirect effect on engagement. How? If people aren't aware of your name change, they might not recognize you in their feed or in search results. This could lead to lower engagement on your posts, especially in the short term.
Both are required by law. HM Revenue and Customs (HMRC): Tell HMRC about your new address to keep tax records accurate. This includes PAYE, Self Assessment, and tax credits.

When changing address in Australia, notify key government bodies like the ATO, Medicare, Centrelink, and Electoral Commission (via myGov or direct), along with financial services (banks, super funds, insurers), utilities (energy, internet, phone), employer, healthcare providers, schools, and update your driver's license/vehicle registration with your state's transport authority. Don't forget mail redirection via Australia Post and notifying subscriptions and other services.
