Parents who applied online for their child to start reception or year 3 in September can collect their offer from April 16.
There were over 7,700 first preference applications this year across the county.
Despite increases in size of the reception year groups and the number of requests for popular schools, Lincolnshire County Council say the majority of children will receive an offer from their first preference.
The county council will post offer letters to parents who applied by telephone or by paper form on the same day.
