Summarize the following:
Before beginning the application process, you will need to figure out if you would be happy as a letter carrier. Like all jobs, this will depend on your personality, lifestyle, and skill set.  The happiest and most effective letter carriers will be "morning people." Most postal carriers start their day at 7 am and finish around 3 pm. If you're an early-riser who would like to avoid rush-hour traffic, you may be an excellent fit.  The typical workday for most mail carriers is a physically strenuous one. Your job will likely consist of a lot of walking and lifting heavy objects. If you do not enjoy physical activity or you have health problems that would make these tasks difficult or impossible, you would probably be better suited for a different job. Unless you live in a dense urban center, you will need to be a skilled driver. The mail needs to be delivered no matter the road conditions. If you are prone to traffic accidents or you find driving to be stressful, this may not be the right career for you. While these jobs used to be listed at the local post office, most countries now use online application systems. Simply visit the appropriate website and use the search function to find jobs near your home.  The United States Postal Service (USPS), Canada Post, and Australia Post all list available positions on the organizations' websites under "Careers" or "About Us."  While most Royal Mail positions in the UK are posted on the company's website, others are posted elsewhere. Use both the Royal Mail's webpage under "Careers" and the government-sponsored website Universal Jobmatch to search for open positions. In general, letter carriers will have qualifications based on levels of physical fitness, driving record, and reading ability.  The USPS requires that all applicants must be citizens or legal residents of the United States and either at least 18 years old, or 16 with a high school diploma. Carriers may also be required to lift up to 70 lbs (about 32 kilos) and have a safe driving record, depending on the position. Successful applicants must also pass a criminal background check, drug screening, medical assessment, and aptitude test specific for letter carriers called Exam 473. Preferential selection will be given to veterans of the US armed forces.  Canada Post requests that all applicants must be able to lift packages weighing up to 22.7 kilos (50 lbs), carry loads up to 15.9 kilos (35 lbs), and climb stairs in inclement weather. They must also have a valid driver's license with a three year satisfactory safe driving record. Applicants will also be evaluated based on their organizational and customer service skills.  Australia Post has different job requirements for different types of "postal delivery officer" dependent on the specific mode of transportation used, including walking. In general, all must be able to lift and carry up to 16 kilos (roughly 35 lbs) and have excellent interpersonal communication skills. Letter carriers in the UK are generally required to lift up to 16 kilos (roughly 35 lbs) and pass an aptitude test. When applying for a delivery driver position, the applicant must have a full UK driving license with no more than 6 penalty points. You will need information about past employment and education records. You will also need to have relevant government identification numbers, such as your social security number if you live in the US, and your driver's license if required. In the US, to claim veteran's preference, you must have a digital copy of your Certificate of Release or Discharge from Active Duty or other proof of past service.
